Applications of Electromagnets

Question 1

What are the five applications of electromagnets?

Answer 1

Tractive = Attraction of a pivoted armature.

Solenoid = Drawing in or out a plunger from a coil.

Lifting = Magnetically attracting magnetic materials for lifting or transportation.

Field coils: coiled conductors in motor and generator field poles to generate momentum.

Transformer windings: Two conductor windings wrapped around a common ferromagnetic core.
