If m is magnetic moment and B is the magnetic field, then the torque is given by
1
\( \overrightarrow{\mathrm{m}} \cdot \overrightarrow{\mathrm{B}} \)
2
\(\frac{|\overrightarrow{\mathrm{~m}}|}{|\overrightarrow{\mathrm{B}}|}\)
3
\(\overrightarrow{\mathrm{m}} \times \overrightarrow{\mathrm{B}} \)
4
\(|\overrightarrow{\mathrm{~m}}| \cdot|\overrightarrow{\mathrm{B}}|\)
