1. A loop in the shape of an equilateral triangle of side l is suspended between the pole pieces of a permanent magnet such that \[\overrightarrow{B}\] is in plane of the loop. If due to a current i in the triangle a torque τ acts on it, the side l of the triangle is :
2. Assertion (A): To produce high magnetic moment from a current carrying cable, it should be turned in maximum number of circular loops. Reason (R): Magnetic moment is directly proportional to number of turns of circular loop for a given length of wire.  
3. A bar magnet of length \( l \) and pole strength \( m \) is placed in uniform magnetic field \( B \) at an angle of \( 60^\circ \) with field. The torque on the bar magnet at this instant will be
4. 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.  
5. Assertion (A): Magnetic field arises due to charge in motion but a system may have magnetic moment even though its net charge is zero. Reason (R): Uncharged magnetic material may have dipole moment.
