If a body moves with a constant speed and at the same time undergoes an acceleration, its motion is said to be
A coil X is moved quickly away from the end Y of a stationary metal bar and a current then flows in X as shown above.
Then
the bar is not a magnet
Y is a north pole
Y is a South pole
Y repels coil X
