A short bar magnet of magnetic moment $0.4 J T^{- 1}$ is place in a uniform magnetic field of $0.16 T$ . The magnet is stable equilibrium when the potential energy is
$- 0.064 J$
$0.064$
Zero
$- 0.082 J$

For stable equilibrium
$U = - M B$
$= - (0.4) (0.16)$
$= - 0.064 J$ .

A short bar magnet of magnetic moment 0.4JT−1 is place in a uniform magnetic field of 0.16T. The magnet is stable equilibrium when the potential energy is−0.064J0.064Zero−0.082J

For stable equilibriumU=−MB =−(0.4)(0.16) =−0.064J.
