A bar magnet of magnetic moment 3.0 Am2 placed in a uniform magnetic induction field of 2×10-5 T . If each pole of the magnet experiences a force of 6 ×10-4 N , then what is the length of the magnet ?
When a bar magnet of magnetic moment ¯¯¯¯¯¯M is placed in a magnetic field of induction field strength ¯¯¯¯B, each pole experiences a force of ¯¯¯¯F then the distance between the South and North pole of the magnet measured inside it is :
