Q

What happens when a current-carring wire is put between magnetic poles?

A

The magnet and the conductor exters a force on each other - this causes the wire to move

17
Q

What is the motor effect?

A

The reason why a wire moves when it is placed between two magnetic poles

18
Q

When will a wire experience the most force in the motor effect?

A

When it is at 90 degrees (perpendicular)

19
Q

When will a wire experience no force in the motor effect?

A

If the wire is parallel

20
Q

In what direction does the force always act in the motor effect?

A

At right angles from the magnetic field and the direction of the currnet
