Measurements

There are few characteristics of these magnets:
It is the simple type of magnet.
These are permanent magnets and mainly composed of Ba (Barium) or Sr Fe12O19 (Strontium Ferrite).
These magnets have good resistance to demagnetization.
These are very cheap and do not have any harmful effect.
These are hard and brittle in nature.
Owing to their low cost, these magnets are used in very wide range of applications, like in motors, loudspeakers, toys, arts and crafts.
The ferrite magnet produces a magnetic field similar to the earth’s magnetic field. Although the magnetic field produced by the earth is quite larger but weaker in strength.
