A 15 turn circular wire loop that lies in the xy-plane has a diameter of 0.30 m. A current of1.5 A travels through the loop such that the current is in the clockwise direction when viewedfrom above the xy-plane. The loop is in a uniform magnetic field: B = +1.5 T j – 2.0T k.(a) What is the magnetic moment of the current loop? (b) What is the torque exerted on theloop by the magnetic field? (c) What is the potential (orientation) energy of the coil in thismagnetic field? As usual, set the potential energy equal to zero when the magnetic moment isperpendicular to the magnetic field. For any vector quantities give the answer in unit-vectornotation.
