Q: What is the principle behind the working of an electric motor?
Solution: An electric motor operates on the principle of the Lorentz force, which states that a current-carrying conductor in a magnetic field experiences a force.
Steps: 5
Step 1: Understand that an electric motor converts electrical energy into mechanical energy.
Step 2: Learn about the Lorentz force, which is the force experienced by a wire carrying electric current in a magnetic field.
Step 3: Recognize that when electricity flows through a wire in a magnetic field, the wire experiences a push or pull due to the Lorentz force.
Step 4: This push or pull causes the wire (or coil) to move, creating rotational motion.
Step 5: The rotational motion of the wire is what powers the motor and does work, like turning a fan or driving a car.
