Lesson 1/Learning Event 1
If a single loop of wire is turned in the magnetic field between a north and south pole of a magnet,
there will be an electrical pressure (voltage) induced or built up in the two sides of the loop.
However, where the loop is turned, one side goes up and the other goes down. Because the two
sides of the conductor in the magnetic field are moving in opposite directions, the induced current
will flow in opposite directions. In other words, the current is alternating in the loop.
