    Moving charges will produce a local magnetic field, but the reverse is also true a changing magnetic field will similarly induce charges to move (ie. produce current). Consider a magnet moving into a coil of wire: A spinal coil of wire with many closely-spaced tums this is called a solenoid is connected to a micro-ammeter as shown in the diagram above. As the magnet moves into the coil, any induced current will be measured by the micro-ammeter. Question On the...
