How does an Electric Motor Work?

The video "How does an Electric Motor Work? (DC Motor)" explains the basics of electricity and magnetism to help understand how an electric motor works. The video demonstrates the creation of an electromagnet. It explains the function of a commutator in a DC motor, which switches the electromagnet's polarity on the armature as it spins. The number of loops on the armature determines the motor's torque, and the spinning motion can be converted into different types of movement to power devices. The video also promotes Brilliant, an educational website offering courses on math and science, including electricity and magnetism.

 Electric motors can seem very mysterious! How do they use electricity to start rotating? Let's break it down step by step to understand how it works. Topics covered in this video: circuits, current, magnets, electromagnets, armature, commutator, brushes, stator, and rotor. This video only covers DC motors.
