STATEMENT: The helicopter, illustrated in the following figure, has a propeller whose metal blade MN, of length L, can be modeled as a conducting rod, where the end M is fixed to the rotor's axis of rotation and the other end N describes a circular trajectory contained in the horizontal plane, with a constant frequency equal to f. At the location where the helicopter is situated, the Earth's magnetic field \(\vec{B}\) has vertical and horizontal components with intensities equal to \(B_V\) and \(B_H\), respectively. Due to the rotation of the metal blade, an induced electromotive force arises in the Earth's magnetic field between the ends M and N, with a magnitude equal to
