How is electromagnetism applied in the refrigerator?

First, a strong magnetic field is applied to the refrigerant, forcing its various magnetic dipoles to align and putting these degrees of freedom of the refrigerant into a state of lowered entropy. The heat sink then absorbs the heat released by the refrigerant due to its loss of entropy.

What is the importance of electromagnetism?

Electromagnetism has important scientific and technological applications. It is used in many electrical appliances to generate desired magnetic fields. It is even used in a electric generator to produce magnetic fields for electromagnetic induction to occur.

What is the application of electricity?

People use electricity for lighting, heating, cooling, and refrigeration and for operating appliances, computers, electronics, machinery, and public transportation systems. Total U.S. electricity consumption in 2020 was about 3.8 trillion kWh and 13 times greater than electricity use in 1950.

How is electromagnetism applied in electrical engineering?

By manipulating the electric current, the magnetic fields can be changed and manipulated as well, which allows more control than permanent non-electric magnets. Electromagnets are commonly used in electrical devices, such as loudspeakers, hard disks, MRI devices, and electric motors.
