disk ferrite magnet

disk ferrite magnet is one of the common disc magnets and widly used! Ceramic (ferrite) magnets are composed of strontium carbonate and iron oxide. They are charcoal gray in color and usually appear in the forms of discs, rings, blocks, cylinders, and sometimes arcs for motors.

In terms of their magnetic properties, the different ferrites are often classified as "soft" or "hard", which refers to their low or high magnetic coercivity.

How to Block Magnets?

Magnetic fields need to be blocked in some situations. For example, a hard drive shouldn't be exposed to magnetism. Military systems are often protected from electromagnetic pulses in the event of atomic detonations. Simple shielding can be accomplished with a plate of iron because the magnetic elements orient themselves in an external magnetic field to cancel it out. The north pole of the iron orients toward the south pole of the magnet, so anything on the other side of the iron plate will perceive a net magnetic field strength of zero.
