Teaching UKPSC Lecturer Mock Test Series 2024 Physics Moving Charges and Magnetism The Magnetic Dipole Moment
A magnet of magnetic moment \(50\hat i\;A{m^2}\) is placed along the x-axis in a magnetic field \(\vec B = \left( {0.5\hat i + 3.0\hat j} \right)\) T. The torque acting on the magnet is
1
\(175\hat kN - m\)
2
\(150\hat kN - m\)
3
\(75\hat kN - m\)
4
\(25\sqrt {37} \hat kN - m\)
