Magnetic circuits are employed to efficiently channel magnetic fields in many devices such as electric motors, generators, transformers, relays, lifting electromagnets, SQUIDs, galvanometers, and magnetic recording heads.
Recording Systems
The most common application of magnetic material is probably in the
increasing number of recording instruments used every day in the office
and the home. For instance, the VHS tape and the 8-mm cassette of
[Fig. 1] are used almost daily by every family with a VCR or cassette
player. The basic recording process is not that difficult to understand
and will be described in detail in the section to follow on computer hard disks.
