Alnico
– AlNiCo (Aluminum-Nickel-Cobalt) cast magnet material.
Alnico Assembly – Holding magnet with excellent
temperature resistance of up to 900°F, typically more
susceptible to demagnetizing forces than other magnet materials.
Anisotropic Magnet – Magnet with a preferred direction of magnetic orientation.
Bipole Electromagnet – An electromagnet design
that has the magnetic coil positioned between two parallel
steel plates that act as the poles - one north and one south.
BHmax – Maximum Energy Product of a given magnet
material expressed in GOe (Gauss/Oersteds) or MGOe (Million
Gauss/Oersteds).
Ceramic – usually used to describe Strontium
Ferrite magnet material.
Ceramic Assembly - Holding magnet potted with epoxy
resistant to 180°F and in general greater resistance
to demagnetizing forces as compared to other magnet materials.
Chip Coolant Separator – removes ferrous and non-ferrous
particles from a coolant flow system. Can be used as a stand-alone
process or if used in combination with filter media, increases
the media’s service life.
Demagnetizer – a device which utilizes an alternating
electrical current to eliminate any residual magnetism in
parts passed through or over its surface.
Demagnetizing Force – critical forces such as temperature,
shock, vibrations and electrical or magnetic currents that
may cause a magnetic material to partially or completely
demagnetize.
Electromagnet – a magnetic device used for holding
or lifting which generates its magnetic field from an electric
current.
Ferrous Material – any material containing iron,
it is therefore magnetically attracted.
Gauss – B (in the CGS system) - unit of measure
of magnetic induction. One gauss is equal to one Maxwell
per square centimeter.
Holding Magnet – a magnetic device designed
to hold ferrous material such as in a fixture or die.
Holding Value – typically measured in pounds,
this is the amount of force required to break a magnet’s
contact from a surface.
Island Pole Electromagnet – A round or rectangular
electromagnet design that has an outer pole and an inner
or "island" pole – one acts as north and
one as south.
L/D Ratio – describes the relationship of the
length of a given magnet to its diameter or surface area
equivalent.
Lifting Magnet – a magnetic device designed
for lifting of ferrous bar stock and plate, usually in a
manual application.
Magnetic Belt Conveyor - a belted conveyor utilizing
a stationary magnet under its belt to assist in transferring
ferrous
parts and scrap materials. This style of conveyor can be
inverted and applied in overhead transfer operations.
Magnetic Flux - Total magnetic induction within a certain area.
Magnetic Drum – a round, cylindrical magnetic
device used to separate ferrous from non-ferrous material,
usually with a stationary magnet and rotating drum. A Magnetic
Drum may also be the rotating component of a magnetic chip
coolant separator.
Magnetic Pulley – a round, cylindrical magnetic
device typically used as a head pulley of a belt conveyor
to attract ferrous material to the belt and then drive the
ferrous material by the friction of the belt. Often used
to transmit torque or to separate ferrous from non-ferrous
material at the discharge end of a belt conveyor.
Magnetic Roller – a round magnetic device used
to directly contact flat or cylindrical ferrous material.
Often used to transmit torque in order to propel sheet,
tube or bar stock.
Magnetic Sheet Fanner – a magnetic device designed
to separate stacked sheet stock. The magnetic fanner induces
magnetism into a stack of sheets causing the individual
sheets to repel each other, this allows the top sheets to
rise for easy removal.
Magnetic Slide Conveyor – a beltless conveyor with
no external moving components, it utilizes magnetic assemblies
that travel under a stainless steel slider plate for transferring
ferrous parts or ferrous scrap materials.
Metal Detector – an electronic device that monitors
a product for tramp metal content. Typically used in a metal
separation system after a magnet to detect non-ferrous materials
such as aluminum and non-ferrous stainless steel.
Non-ferrous Material – material that does not
contain any iron and is therefore not magnetically attracted.
Orientation – Direction which an anisotropic magnet should be magnetized to optimize the magnetic field properties.
Permanent Magnet – any of the various magnetic
materials, a permanent magnet has a magnetic field energized
by the flow of the electrons of the material itself.
Permanent Magnet Assembly – a magnetic device
that is designed using a combination of permanent magnet
material and pole pieces, various configurations allow for
varying applications.
Pole Piece – metal with a high ferrous content
that is used to direct a magnetic field.
Rare Earth – commonly used to describe high
energy magnet material such as NdFeB (Neodymium-Iron-Boron)
and SmCo (Samarium-Cobalt).
Rare Earth Assembly – Holding magnet designed
with a temperature range comparable to ceramic, but with
the greatest holding values as compared to other magnet
materials.
Reachout – a type of magnetic design or term
that describes a magnet’s strength characteristics
at a distance from its surface.
Saturation – Condition where all magnetic moments have become oriented in one direction.
Stabilization – Exposing a magnet to demagnetizing influences as intended to the application, to prevent irreversible loss during the magnets operational application.
Tramp Iron – unwanted ferrous material in a
product flow such as nuts, bolts, wrenches or scale.
Tramp Metal – unwanted ferrous and non-ferrous
material in a product flow such as bolts, aluminum or stainless
steel.
