Q: What is the principle behind the operation of an electric motor?
Solution: Electric motors operate on the principle of the Lorentz force, where a current-carrying conductor in a magnetic field experiences a force that causes it to rotate.
Steps: 6
Step 1: Understand that an electric motor uses electricity to create motion.
Step 2: Know that a conductor (like a wire) carries electric current.
Step 3: Recognize that a magnetic field is created by magnets or electromagnets.
Step 4: Learn about the Lorentz force, which is the force experienced by the conductor when it is in the magnetic field.
Step 5: Realize that this force causes the conductor to move or rotate.
Step 6: Understand that the rotation of the conductor is what creates mechanical motion in the motor.
