The most efficient method of demagnetizing a magnet is to use an alternating current?
dc with reversing and step-down control
What are ways to magnetize something?
Rub it with a magnet if it is metallic.
3 ways on how to make a magnet stronger?
What I learned was that there is and might be only 2 ways and that is to increase the current (add more batteries) or add more coils..
What are five ways electromagnetic waves differ from each other?
need to describe in five ways how electronic waves differ each other
What are five objects that are attracted to magnets?
Household items: paperclip scissors knife another magnet steel fridge (not)
How is magnetizing an object the opposite of demagnetizing a magnet?
Demagnetizing. Place the magnet at the opposite end of the metal from where you magnetized it. Again, the magnet must make as much contact with the metal as possible. Rub the metal with the magnet in the opposite direction that you used to magnetize it.
How can you demagnetizing a magnet?
To demagetize a magnet you could smash one if the ends with a hammer. this will cause the order of atoms to rearange so that it's not magnetic.
The most efficient method of demagnetizing a magnet is to use an alternating current?
dc with reversing and step-down control
Which type of magnet can easily be magnetized and demagnetized?
An electronic magnet is by far the easiest because you magnetize one by hitting a button (or for home made magnets) connecting a wire, and demagnetizing by hitting the button again or disconnecting the wire.
How could an old magnetic field be preserved in rocks?
Because lava can melt iron (demagnetizing it) and when it solidifies, it will pick up whatever magnet field it is currently subject to, thus locking in a record of the magnet field at the time in history.
What are the ways of demagnetize the magnet?
By keeping them in magnet keepers
What are some ways earth acts like a magnet?
the core is basically a magnet, right?
What are ways to magnetize something?
Rub it with a magnet if it is metallic.
How are electro magnet like bar magnets?
a bar magnet and a electromagnet are alike in many ways. the are alike because both of them are magnets. but there are plenty other ways they are alike
What are some ways that the Earth is like a magnet?
I like peanuts
What are five ways in which organisms are similar?
What are the five ways in which organisms are similar?
Are five magnets five times as strong as one magnet?
The answer depends on whether the five magnets are all the same! But assuming they are, the answer is yes.
