Answer: A.
motor
Motor uses an electromagnet to convert electrical energy into mechanical energy.
Explanation:
Electrical engines adhere to one side hand rule. As indicated by Fleming's left-hand rule, the thumb, index finger and the center finger are extended commonly opposite to one another.
At that point, if the pointer demonstrates the bearing of the attractive field, the center finger shows the course of the present as attractive field and current travel commonly opposite to one another, at that point, the thumb will speak to the heading of power or movement.
So as indicated by this standard, the electromagnet present in an electric engine will deliver an attractive and electric field a commonly opposite way and because of these fields, the pole will pivot prompting mechanical power.
In this way, the electrical vitality delivered by the electromagnet is changed over to mechanical vitality in an electric engine.
