Question

in a motor, the armature: a) sets up the magnetic field b) transfers current c) is an electromagnet d) uses segments to reverse current

Explanation:

In an electric - motor, the armature is a coil of wire that when current passes through it, it becomes an electromagnet. The field magnet sets up the magnetic field, not the armature. The commutator (not the armature itself) uses segments to reverse current, and the brushes transfer current.

Answer:

C. Is an electromagnet
