5.1 Magnets and Magnetic Fields
Magnetism plays an important role in the field of electrical engineering. Construction of almost all electrical gadgets, equipment, and machines are done using the properties of magnetism, like in transformers, electrical rotating machines, i.e., generators and motors, relays, cutouts, electrical bells, etc.
The word “magnetism” originated from the city of Magnesia (now called ...
