  ELECTRO MAGNETIC INDUCTION Summary: Electromagnetic induction is that the method of generating current with a magnetic flux . It occurs whenever a magnetic flux and an electrical conductor, sort of a coil of wire, move relative to a minimum of each other . As long because the conductor may be a component of a loop , current will flow through it whenever it crosses lines of force within the magnetic flux . The Current Produced by a Magnet The device with the pointer in an ammeter. It measures this that flows through the wire. The faster the magnet or coil moves, the greater the number of current that's produced. If more turns were added to the coil or a stronger magnet were used, this is often ready to produce more current also . The direction of this that's generated by a moving magnet are often understood as, If the magnet is moved back and forth repeatedly, this keeps changing direction. In other words, AC (AC) is produced. AC is electrical current that keeps reversing...
