Select all that are true.
a. An object or matter acted upon by a magnetic torque is called a magnetic dipole.
b. Magnetic torque on a magnetic dipole in a uniform magnetic field is the cross product of the magnetic dipole moment and the magnetic field.
c. Torque on a magnetic dipole in a magnetic field is such that the dipole tends to align the dipole moment with the magnetic field.
d. Magnetic dipole moment is the torque on the two poles of a permanent magnet.
e. Torque on a magnetic dipole in a magnetic field is such that the dipole tends to decrease the angle between its plane and the magnetic field.
