HINT:
When the ignition switch is in the ON position, current flows from the battery to the alternator. The reason for this is to prepare the alternator to supply electricity before starting the engine. Most alternators used in modern vehicles generate electricity by rotating a magnet, called a rotor. This magnet (rotor) is not a permanent magnet, but an electromagnet, that generates a magnetic force when electricity flows through it. Therefore, it is necessary to allow some electricity to flow through the alternator before it starts to rotate to assist in generating electricity once it commences rotation. |
