A rectangular current loop with side lengths of 4.0 cm and 6.0 cm carries a current of 10 A. What is the magnetic dipole moment of the loop?
A circular coil of radius 7.5 cm is wound with five turns and carries a current of 4.2 A. If the coil is placed in a uniform magnetic field of magnitude 4.5 T, what is the magnitude of the maximum possible torque that the magnetic field can exert on it?
A conducting loop has 50 square turns with sides 15 cm long. The loop is placed in a uniform magnetic field of 0.80 T. Find the current through the loop needed to create a maximum torque of 9.0 N⋅m.
