The magnetic field around an electromagnet is produced by ________.
A)a current flowing through the winding
B)the conductor?s permeability
C)a permanent magnet
D)the laminated iron core

Question

Quizplus · Accepted Answer

The magnetic field around an electromagnet is produced by a current flowing through the winding. When a current flows through a wire, it creates a magnetic field around the wire. When the wire is wrapped into a coil, the magnetic field is amplified, creating a strong magnetic field around the coil, which is the basis of an electromagnet.
