How many of devices you identified inside the control room need to magnetism to operate

A typical control room consists of  an audio console, microphones, computers, audio interference, studio monitors and disks players needs magnetism to operate.

Further Explanation:

Electromagnetism consists the study of electricity and magnetism, and how they are connected to each other. An electromagnet is a temporary magnet, when electric current is flowing through magnet, generates a magnetic field . Few electromagnets create very strong magnetic fields when current is flowing through them. Magnetism and electromagnetism are fundamental concepts in Physics, the main difference is magnetic surrounds only phenomena due to magnetic forces, whereas electromagnetism surrounds phenomena due to both magnetic and electric forces. A sample picture of a generic control room is attached.
