An electric motor is a device that converts electrical energy into mechanical energy. It works by using the principle of electromagnetism, which is the interaction between electric currents and magnetic fields. There are different types of electric motors, but the basic idea is the same: a coil of wire carrying an electric current rotates inside a magnetic field, creating a force that makes the coil spin. One of the simplest electric motors is a DC motor , which runs on direct current (DC) from a battery or a power supply. A DC motor has two main parts: a rotor and a stator. The rotor is the part that spins and has a coil of wire wrapped around an iron core. The stator is the part that stays still and has a permanent magnet or an electromagnet. The coil of wire on the rotor is connected to a split ring called a commutator, which rotates with the coil and switches the direction of the current every half turn. This ensures that the coil always experiences a force in the same direc...
A boat motor fizzled and nobody could fix it, so they got a Mechanical Designer with 40 years experience.

He examined the motor cautiously, through and through.
Subsequent to looking things over, the person ventured into his sack and took out a little sledge.
He tenderly tapped something. Right away, the motor burst once again into life.
The motor was fixed!
after 7 days the proprietors got his bill for $10,000.
"What?!" the proprietors said. "You scarcely did anything. Send us an organized bill."
The answer just said:
Tapping with a sledge: $2
Knowing where to tap and how much powerfully to tap: $9,998
