Final answer:
Electric motors are the type of starters that use an electromagnetic switch containing two separate, but connected, electromagnetic windings to engage the starter drive and control the current from the battery to the starter motor. These motors contain wire loops in a magnetic field.
Step-by-step explanation:
Electric motors are the type of starters that use an electromagnetic switch containing two separate, but connected, electromagnetic windings to engage the starter drive and control the current from the battery to the starter motor. These motors contain wire loops in a magnetic field. When current is passed through the loops, the magnetic field exerts torque on the loops, which rotates a shaft. The current is reversed every half rotation so that the torque on the loop is always in the same direction.
