Final answer:

To change the rotation direction of electric motors, reverse the current by changing polarity using switches.


Explanation:

In electric motors, to change the direction of rotation, the current passing through the motor needs to be reversed by changing the polarity of the current. This reversal in current flow can be achieved using double-pole, double-throw switches, which are commonly used in applications like automatic car gates to control the motor direction.
