Which of the following statements are correct ?
(1) In a uniform magnetic field, torque on the magnetic dipole is 0 when potential energy is minimum.
(2) In a uniform magnetic field, torque on the magnetic dipole is maximum when potential energy is 0 .
(3) Net force on the magnetic dipole is always zero in magnetic field.
(4) Torque on the magnetic dipole is directly proportional to magnetic flux density.
