A student places a small steel ball on a smooth board. When she brings the North pole of a bar magnet near it, the ball rolls towards the magnet. What will happen if she turns the magnet around and brings its South pole near the same steel ball?
The steel ball will roll away due to repulsion
The steel ball will roll towards the magnet again
The steel ball will remain stationary without moving
The steel ball will start spinning in circles
Solution
Unmagnetized magnetic materials like steel are attracted to both the North and South poles of a magnet.
