Ferrite Block Magnets 25x11x6mm Set of 20 Magnets for Science project & fun
SKU - mgnet_fn_12
A ferrite is
a type of ceramic compound
composed of iron(III)
oxide (Fe2O3) combined chemically with
one or more additional metallic elements. They are both electrically
nonconductive and ferrimagnetic,
meaning they can be magnetized or
attracted to a magnet. Ferrites can be divided into two families based on their
magnetic coercivity,
their resistance to being demagnetized. Hard ferrites have
high coercivity,
hence they are difficult to demagnetize. They are used to make magnets, for
devices such as refrigerator
magnets, loudspeakers and
small electric
motors. Soft ferrites have low coercivity. They
are used in the electronics industry to make ferrite cores for inductors and transformers, and
in various microwave components.
Ferrite compounds have extremely low cost, being made of iron oxide (i.e.
rusted iron), and also have excellent corrosion resistance. They are very
stable and difficult to demagnetize, and can be made with both high and low
coercive forces.
Utility:
