\( \overrightarrow{\mathrm{m}} \cdot \overrightarrow{\mathrm{B}} \)
\(\frac{|\overrightarrow{\mathrm{~m}}|}{|\overrightarrow{\mathrm{B}}|}\)
\(\overrightarrow{\mathrm{m}} \times \overrightarrow{\mathrm{B}} \)
\(|\overrightarrow{\mathrm{~m}}| \cdot|\overrightarrow{\mathrm{B}}|\)

Answer 1

Concept:

If m is the magnetic moment and B is the magnetic field, then the torque (τ) on the magnetic dipole is given by the vector cross product of the magnetic moment and the magnetic field.

Formula Used:

τ = m × B

This formula represents the torque as the vector cross product of the magnetic moment and the magnetic field.

Conclusion:

Hence, the correct answer is option 3.
