Heating or hammering a permanent magnet can make it less magnetic, or even remove its magnetism completely. Interactive Reader 409 Magnetism SECTION 3 Name Class Date Electric Currents from Magnetism continued GENERATORS AND AC CURRENT The diagram below shows the amount of current an AC generator produces as the loop rotates. There is no current in the loop. The Core of the Matter Scientists think that the Earths magnetic field is made by the movement of electric charges in the Earths core. A single wire wrapped into a coil creating a magnetic field is called a _____. Before the loop begins to rotate, it is perpendicular to the magnetic field. Section 1 Magnets and Magnetism.
