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.
