Question

What produces the magnetic force of an electromagnet?(1 point) a. magnetic fields passing through the device b. movement of charged particles through the wire c. static charged particles on the wire d. positive and negative charges repelling each other

Answer 1

b. Movement of charged particles through the wire.

Explanation: an electromagnet's magnetic field (and resulting force) is produced by electric current—moving charges—in the coil. Static charges do not produce a magnetic field.
