To find the torque exerted on a bar magnet with a magnetic moment \(\vec{M}\) placed in a magnetic field \(\vec{B}\), we can use the formula for torque in the context of magnetic moments. The torque \(\vec{\tau}\) acting on the magnetic moment in a magnetic field is given by the vector cross product: \[ \vec{\tau} = \vec{M} \times \vec{B} \] ### Step-by-Step Solution: ...
