To achieve the optimum pull force 100% contact area must be achieved using the recommended armature plate. The force will be affected if other
material specifications, thicknesses and surfaces are used, or if the armature fails to make positive contact over the full diameter of the face of the
magnet. Where misalignment is likely to be an issue we recommend that an oversized armature plate is used to ensure 100% full contact, this
however will reduce the stated pull force by approximately 10%.

Lifting magnets
Magnetic lifters are quicker, easier and safer to
use than slings, chains, hooks and grabs, and do
not mark the load.
Onboard switching and permanent magnet technology
mean installation and operation could not be easier
and running costs are non-existent.
Access is only required to the load's top face,
allowing for more efficient storage and handling.
Ultralift Plus
The world's safest lifter
Lifts up to 2000kg (flat) 800kg (round)
3 safety features:
■ Locking switch handle mechanism
■ Unique 'Safety Shim': pre-test any load to ensure a
3:1 safety factor
■ Locking eye mechanism: magnet cannot be
switched off while holding a load
A
3:1SAFETYFACTOR
B
The patented 'safety shim'
allows pre-testing of the
load to be lifted, irrespective
of weight, material type,
material thickness and surface
condition. If the load passes a
3:1 safety factor is guaranteed.

The chucks can be partially magnetised to aid the correct positioning of
the workpiece. Grooved rings in the top plate assist in visual positioning
to aid quick changeover in set up. Excellent for holding thin ring-shaped
components that can be subject to radial distortion. Removable handles
allow easy switching.
Dynamically balanced to enable use at high rpm. All metal top plate and
a rugged, industrial build ensures accuracy and longevity. Through-bore
(except the NR100C) allows through-flushing of coolant during machining.
The unique top plate configuration concentrates the magnetic
energy on to the face of the chuck.

Guide to magnet materials
When choosing a magnet material for an application you should take the
following factors in to consideration:
■
■
■
Flux requirement of the application
Maximum operating temperature
Likely exposure to corrosive conditions
■
■
Magnetic stability
Size / weight limitations
What strength/flux of magnet do you need?
This table (right) shows the comparative magnetic
strengths of the same volume of the four main
magnet materials in terms of their maximum
energy products (BHmax) in CGS or SI units and
their typical pole face flux densities.
Neodymium is the most powerful magnet
material available. It is ideal for applications where
high flux density is required or where space is at
a premium.

Corrosion
Another potential cause of performance loss is a breakdown of the
magnet’s composition due to corrosive environmental effects.
The table shows relative corrosive resistance for each material
when uncoated. As neodymium’s corrosive resistance is poor it is
usually sold with a protective coating, normally either nickel or zinc.

When a depth of field is required for attracting, switching or
actuating across an air gap use a single pole of a magnet.
N
S
Single pole operation
Magnet flux crosses a gap but
has a diminishing strength field.
Clamping, holding or lifting?
Two pole operation (horseshoe, button or pot magnet)
Two pole or multi-pole magnets are designed for holding, clamping
or lifting when in direct contact with a ferro-magnetic surface.
N
S
Two pole operation
Magnet flux does not travel as
far but is stronger.
Pot magnets
Both north and south pole are on one face of the magnet, similar to button
and horseshoe magnets.
Steel pot – North pole
Non-magnetic material
Magnetic material – South pole
Button magnet
Horsehoe magnet
North pole
The magnet material is encased inside a steel pot. The pot is part of the
magnetic circuit. The poles are concentric.
The depth of the magnetic field is shallower than that of magnets with
poles further apart, e.g. horseshoe magnets, but grip in intimate contact
is generally superior.
Maximum operating temperature of pots is lower than the magnet
material used because of the different thermal expansion rates of
the material and the pot. Exposure to temperatures higher than the
recommended max. can cause units to come apart.
Other features
• No stray flux as magnetism is retained in a closed circuit
• Pot screens magnet material from demagnetising effects
• Pot is machinable
• Can be inserted into steel without adverse effects (not the case with
unscreened magnets)

Glossary of magnetic terms
Air Gap
A non-magnetic discontinuity in a magnetic circuit (i.e. the
distance between two magnetic poles), this gap often includes
other materials such as brass, aluminium or paint
Anisotropic Magnet
A magnet which has a preferred direction of orientation so
that the magnetic characteristics are optimum in one preferred
direction
Closed Circuit
This exists when the flux path external to the permanent magnet
is confined within high permeability materials which contain the
magnet circuit.
Coercive Force, Hc
The demagnetising force necessary to reduce observed
induction B to zero after the magnet has been brought to
saturation. Coercive force is measured in Oersteds or more
recently A/m and kA/m.
Curie Temperature, Tc
The temperature at which a material loses its permanent
magnetic properties completely and is no longer able to hold
magnetism
Demagnetisation Curve
The second/left quadrant of the hysteresis loop, generally
describing the behaviour of magnetic characteristics in actual
use. Also known as the B-H curve.
Ferromagnetic Material
A material whose permeability is very much larger than one,
and which exhibits hysteresis magnetising and demagnetising
characteristics. The greater the flux carrying potential, the bigger
the value i.e. one to several thousands.
Flux
Magnetic flux is the condition existing in a medium subjected
to a magnetising force. This value is quantified by E.M.F.
(electromotive force). This measurement of force in cgs units is
a Maxwell.
Fringing Fields
Leakage flux particularly associated with edge effects and
leakage patterns in a magnetic circuit.
Gauss
Lines of magnetic flux per square centimetre. Gauss is
measured in cgs units, Maxwell lines and Webers per square
metre or Tesla in the Si system.
Hysteresis Loop
A closed curve calculated by plotting corresponding values of
magnetic induction: B on the abscissa against magnetising
force H.
Induction, B
This is the magnetic flux per unit area of section in the applied
magnetic direction of flux. This is measured in Gauss.
27
Intrinsic Coercive Force
This is a measure of the resistance of the magnet material to
a demagnetising force. Permanent magnets with high intrinsic
coercivity values are usually classified as 'hard' permanent
magnets. Intrinsic coercive force indicates magnetic stability at
high temperatures. Also see stabilisation.
Irreversible Loss
This is the partial demagnetisation of a magnet material when
introduced to external factors such as high/low temperatures
and demagnetising fields. Losses can only by rectified by
remagnetisation. However, magnets can be stabilised to prevent
the variation of performance caused by irreversible losses.
Isotropic Magnet
A magnetic material which does not have a preferred direction
of magnetic orientation and therefore can be magnetised in any
direction without the loss of magnetic characteristics.
Knee of the Demagnetisation Curve
The point at which the B-H curve ceases to be linear. If the
operating point of the magnet falls below the knee, the magnet
will not be able to recover full magnetic potential without the
application of a magnetising force.
Leakage Flux
This is the loss of magnetic flux which occurs through leakage
caused by saturation or air gaps introduced into the magnetic
circuit. This induces a loss of efficiency in the circuit which
cannot be recovered.
Length of Air Gap, Lg
Indicates the length of the central flux path across an air gap.
Load Line
A line drawn from the origin of the Demagnetisation Curve with
a slope. The intersection of the -B/H curve and slope represents
the operating point of the magnet. Also see Permeance
Coefficient, Pc
Magnetic Circuit
An assembly consisting of some or all of the following:
permanent magnets, ferromagnetic conduction elements, air
gaps, electrical currents.
Magnetic Flux
The total magnetic induction over a given area.
Magnetising Force, H
The magnetomotive force per unit length at any point in a
magnetic circuit. This is measured in Oersteds.
Magnetomotive Force, F
This is the potential magnetic difference between any two
points.
Maximum Energy Product, BH max.
There is a point at the Hysteresis Loop at which the product of
magnetising force H and induction B reaches a maximum. This
maximum value is called the Maximum Energy Product and is
measured in Mega Gauss Oersted, MGOe.
Oersted, Oe
A unit measure of magnetising force (cgs). This is equivalent to
Ampere Turns per Inch (S.I.).
Permeance Coefficient, Pc
Ratio of the magnetic induction to self demagnetising force. This
is also known as the 'load line' or operating point of the magnet.
Pull Gap
Usually illustrated in graph format, these curves are a
representation of the relationship between the attractive force
exerted by a magnet on a soft magnetic workpiece and the
distance between them. Pull Gap curve diagrams are useful
when selecting a magnet for a particular tractive or holding
application.
Reluctance, R
Reluctance is the resistance in a magnetic circuit and is related
to the magnetomotive force, F and magnetic flux (R =F/
magnetic flux) where F is the magnetomotive force.
Remenance
Remenance is the magnetic induction which remains in a
magnetic circuit after the removal of an applied magnetising
force. If there is an air gap in the circuit, the remenance will be
less than the residual induction Br.
Residual Induction Br
This represents the maximum flux output from a given magnet
material measured at the point where the Hysteresis Loop
crosses the B axis at zero magnetising force.
Return Path
A magnetic circuit which provides a low reluctance path for the
magnetic flux. Reversible Temperature Coefficient A measure of
the reversible changes in flux caused by temperature variations.
Saturation
This is the condition whereby a magnet or ferromagnetic
material has reached a maximum value and an increase in
the appliance of magnetising force produces no increase in
induction i.e. saturation flux densities for steels range from
16,000 to 20,000 Gauss.
Stabilisation
The process where a magnet is exposed to demagnetising
influences expected to be encountered in operation. The
exposure to these demagnetising influences such as high or low
temperatures or external magnetic fields prevents irreversible
losses during actual operation.
