Advantages and disadvantages of electromagnets

Answer 1

There are many reasons why electromagnets shouldn't be used. For example, permanent magnets are better to use economically because there is no cost of operation, like an electromagnet. There is also no maintenance or hardly any setup required. For permanent magnets, they can be used for a lot longer than electromagnets becausecan be used in hazardous places and are they are unaffected by shock or vibrations. Electromagnets require electricity to run, which costs money. They also burnout or lose its magnetism after a while.

There are also many reasons why electromagnets should be used. For an electromagnet, a person could easily control the power of the magnetism, unlike the permanent magnet which has the same intensity throughout. A person could also turn the power of the magnet on and off, which can become useful in certain situations. An electromagnet can also be made stronger than permanent magnets. The electromagnet also has a good field of depth, unlike the permanent magnets limited field depth.

Answer 2

Magnetic storage holds much more data, but uses mechanical parts (motor).

Theoretically slower than SSDs (Solid state drives) because they use integrated circuits and could be accessed almost instantly. Magnetic storage requires motion ( the disk to spin) instead of solidly electronic storage.

Answer 3

1. Advantage of electromagnets is that they can be turned on and off by using the switch.
2. Another advantage of Electromagnets is that they can be made weaker or stronger. The more coils it have, the more stronger it is.
3. One more advantage of electromagnets is that you can switch it poles.

Answer 4

no physical attachment necessary

will disrupt the magnetic orientation of surrounding objects

Answer 5

an electromagnet requires electricity and you will have to pay for it. permanent magnets are always on and you can change the strength of it.
