The Net Force On A Current Loop In A Uniform Magnetic Field Is Zero The Magnetic Force On The Voice Coil Of A Loudspeak 1 (41.64 KiB) Viewed 14 times

The net force on a current loop in a uniform magnetic field is zero. The magnetic force on the voice coil of a loudspeaker is nonzero because the magnetic field at the coil is not uniform. A voice coil in a loudspeaker has 55 turns of wire and a diameter of 1.40 cm, and the current in the coil is 0.920 A. Assume that the magnetic field at each point of the coil has a constant magnitude of 0.210 T and is directed at an angle of 60.0 outward from the normal to the plane of the coil (the figure (Figure 1)). Let the axis of the coil be in the y-direction. The current in the coil is in the direction shown (counterclockwise as viewed from a point above the coil on the y-axis).
