Question

Research 4 types of technology that we have in our world that are related to either magnetism or electromagnetism. The technology can be directly related to these topics or just a snowball effect and only somewhat related to them.
Yo should include:
3 examples of technology
Explanation how the technology helps humans (or will help them in future)
Explanation how the tecnology is related to magnetism or electromagnetism

Answer 1

1) Electromagnets: These magnets are formed by wiring a number of turns around a metal object and when current is passed through them, the metal behaves like a magnet. It is used in electric bells, communication purposes specially in telephones.

2) Medical Sciences: In medical sciences, we use MRI, magnetic resonance imaging process, which allows doctors to see through ones' body's muscles, ligaments more clearly to help the patient(s).

3) Computers: The magnetic strip is been used for data storage from very long time. It stores the information by rearranging the particles on a magnetic piece.

4) Veterinary magnets: The items like nails, or other sharp metal objects which the animals might eat on the grass can harm them very seriously and it is quite difficult to remove them. The people feeding the animals have learned to use magnets which will attract metal pieces and will finally be out through their excretory system.
