- Two small bar magnet are placed in a line at certain distance d apart if the length of each magnet is negligible comapared to d the force between them is inversely proportional to
- Calculate torque and force acting on the current carrying loop.

- A wire of length l is bent in the form of a circular loop with a no of turns and is suspended in a magnetic field of intensity B. Find the expression for the maximum torque produced on the circular loop when a current I is passed through it.
- MUST EVERY MAGNETIC CONFIGURATION HAVE NORTH POLE AND SOUTH POLE AND CAN WE THINK OF MAGNETIC FIELD CONFIGURATION WITH THREE POLES ?
- A MAGNETISED NEEDLE IN A UNIFORM MAGNETIC FIELD EXPERIENCES A TORQUE BUT NO NET FORCE. HOWEVER, AN IRON NAIL NEAR A BAR MAGNET EXPERIENCES A FORCE OF ATTRACTION IN ADDITION TO TORQUE. EXPLAIN

- A nickel bar magnet is heated to 500oC and then cooled in free space, which is devoid of any magnetic field. Will the bar retain magnetism?
