5 Awesome Science experiments

Each pole of magnet of length 20 cm in a magnetic field of induction 0.2 T experiences a force 20 N. The magnetic moment of magnet is

A magnetic needle is kept in a non uniform magnetic field . It experiences

A short bar magnet of magnetic moment 0*9JT^-1 is placed with its axis at 30^@ to a uniform magnetic field. It experiences a torque of 0*063J . Calculate the magnitude of magnetic field. In which orientation will the bar magnet be in stable equilibrium in the magnetic field?

A short magnet placed with its axis making an angle with a uniform external magnetic field of induction B experiences a torque (tau) . If the magnet is free to rotate, which orientation would correspong to its stable and unstable equilibrium.

A bar magnet is placed inside a uniform magnetic field, What does in experience?
