A magnet of magnetic moment `50hati Am^(2)` is placed along the x=axis in a uniform magnetic field `vecB = (0.5 hati + 3.0 hatj)T` . What are the net force and torque experienced by the dipole ?

Explanation

For a uniform field , net force is zero .
As , `vectau = vecM xx vecB`
`implies vectau = (50 hati ) xx (0.5hati + 3.0 hatj) = 150 hatk = `Nm .
