How has the understanding of forces and magnets help in everyday life?

Question

I would like to find out not only how magnets help in everyday life but how the understanding has helped. It would also help if you could tell me the sources you used to support your answers.

Answer 1

yes, it helped created electricity with turbine stations from waterfall, wind, and dam.

Answer 2

I work as a magnetic resonance imaging technologist and the knowledge we have from magnets save thousands of lives every day.
An MRI machine works on a basic principle called the Larmour Frequency, which uses a radio wave to cause brief chemical changes inside of atomic structure. A radio wave is put into the body, it is absorbed by the atoms and the radio wave is turned off. Then, because the atom can't stand to be in that state, it gives the radio signal back off and we can listen to it on the way out.

None of this can be achieved (with current technology...) without the use of magnets. Giant magnets. The most commom MR magnet is 15,000 Gauss, or 1.5 Tesla in strength. More and more 3.0 Tesla machines are coming into the marketplace, yielding even more detailed pictures faster than has ever been achieved before.

Magnetic technology has revolutionized medical imaging practice in the past twenty years.

Answer 3

Magnetism is short for electromagnetism, and light is electromagnetic radiation. The scientific endeavor to understand magnetism is inseparable with that to understand electricity, and I believe some of the benefits of electric power and electronics are quite evident in our surroundings.

And of course you have the whole invention of the compass thing.

Answer 4

Automobiles (starters, spark for ignition, generators, etc...) - communication (speakers, microphones, chokes, solenoids, etc...) - appliances (from the step down transformers on the poles to all electric motors, electronic devices, electric clocks, etc....) - without an understanding of magnetic fields and the inventions they have led to, life would be pretty boring indeed.

Answer 5

BIGGEST HELP EVER...someone attached a magnet to a writing board or other object to create...REFRIGERATOR MAGNETS to hang stuff up and leave notes in plain site without losing/wasting paper

Answer 6

the use of magnets is if you think just a little ,,.. life as we know it today would not be possible without them,, from electricity to the mundane task of keeping your cabinets closed ,,,there use is so widespread and diverse theres no time to type it all (there everywhere )

Answer 7

Electric motors, fan, cars, turbines, practically everywhere.

Answer 8

U WANT AN EXCUSE NOT TO DO UR PHYSICS HOMEWORK.....
anyhow....y not study the phenomena if it exist judt to become a better human being...
whatever dude....
