Question

If a motor is spinning and you suddenly reverse the direction of the magnetic field, what happens to the rotation of the motor?

Accepted Answer

When you suddenly reverse the magnetic field inside a spinning motor, the motor experiences a powerful force pushing it in the opposite direction. Think of this like running forward and someone suddenly grabbing your shoulders to pull you backward; your body has to fight its own momentum to change course. At first, the motor will slow down very quickly. It will stop turning for a tiny fraction of a second. Then, it will start spinning in the new direction. This process is called plugging. Because this creates a huge spike in electrical current, it puts a lot of stress on the motor parts. If the motor is big or moving fast, this sudden flip can cause it to overheat or even break.
