Uses of Electromagnet

An electromagnet is a type of magnet in which a magnetic field is created by electricity. The use of electromagnets is given here to help students understand the topic better.

Uses of Electromagnet

Electromagnets can be considered as temporary magnets that work with the help of electricity. The magnetic strength of an electromagnet can easily be changed by changing the magnitude of the current and its polarity by changing the direction of the current.

Electromagnets are used every day in a variety of applications. For example, large cranes used in landfills use electromagnets. Electromagnets are also widely used in many electronic electronic devices.

Uses of Electromagnets

  1. Generators, motors, and transformers
  2. Electric buzzers and bells
  3. Headphones and loudspeakers
  4. Relays and valves
  5. Data storage devices like VCRs, tape recorders, hard discs, etc.
  6. Induction cooker
  7. Magnetic locks
  8. MRI machines
  9. Particle accelerators
  10. Mass spectrometers

Most residential electrical appliances use electricity as the main principle of operation. There are some electrical appliances in the home such as electric fan, electric bell, induction cooker, magnetic locks etc.

Sending electricity to an electric fan turns on the motor and turns the fan panels and when a button is pressed on the bell of electricity, electrical energy energizes the coil and the bell

The use of electromagnets is also seen in medicine. An MRI scan, abbreviated as magnetic resonance imaging, is a machine that uses an electromagnet. The device can scan all the tiny particles in the human body with the help of electricity.

Data in electronic books, devices and phones are stored in bytes and bits in an electromagnetic format. Computer hardware also has a magnetic stripe for electromagnetism. Even in the old days, electricity played an important role in storing data on VCPs and VCRs.

Without electromagnets, the cell phones and telephones we used to make long-distance calls could not take pictures. Electromagnetic vibrations and signal interactions make telephone and telephone much more accessible.
