1. Assertion (A): When a straight wire carrying current is placed along the axis of a current carrying ring, it starts rotating about the wire. Reason (R): Charged ring will experience a torque when current carrying cable will pass through its axis.  
2. Assertion (A): The poles of magnet cannot be separated by breaking into two pieces. Reason (R): The magnetic moment will be reduced to half when a magnet is broken into two equal pieces.
