12.3 The motor effect

Card 1 of 21

State the three conditions needed for the motor effect.

A

The sides carry currents in opposite directions through the same field.

B

To convert rotations per minute to rotations per second, divide by 606060. The time per rotation is t=1n\boxed{t = \dfrac{1}{n}}t=n1​​.

C

For a perpendicular conductor, the force equation is F=BIlF = BIlF=BIl, and magnetic flux density is measured in tesla (T\text{T}T).

D
  • A current flows in the conductor.
  • The conductor is inside a magnetic field.
  • The conductor is not parallel to the field.
