Effect of magnetic field on current conductor

description

In the facility a horseshoe magnet. Between its poles is the rib of a coil of covers.  When direct current flows through the binding coil, the magnetic field will exert a force on the side of the coil, which is trapped between the poles of the magnet, and the coil will perform an amplitude to the right or left, depending on the current trend on the side of the coil (according toLenz's law). Detaching the circuit will return the coil to swing around the axis of the fixture
