2 - the plane of the frame along the magnetic flux - across the m. p 3 - the axis of rotation in the plane of the frame and horizontal to the surface of the Earth 4 the industrial current frequency 50 Hz - this is the sound frequency which will be induced by the electric field of the light wire in the telephone wires will be low hum 6 the moving charge
