Question

These questions are all about magnetic fields and electric motors:

Part I. Fill in the blanks. Motors are devices that convert toenergy rt_energy int The basic principle behind the simple DC motor is that wires that carry when placed in regions of space that have experience Only sections of wire that carry current in a direction experience forces to a magnetic field The speed at which the rotor of a motor spins depends on three important factors: , and The direction that the rotor of a motor spins depends on the rule.

Answer 1
