An electromagnet can be created as fast as you can wrap copper wire around a nail and attach the ends to a battery.

How long does it take for a magnet to lose its power and become demagnetized?

The time it takes for a magnet to lose its power and become demagnetized depends on factors like the material of the magnet and how it is used. In general, permanent magnets can retain their magnetism for a long time, even decades or centuries. However, external factors like high temperatures, strong magnetic fields, or physical damage can cause a magnet to lose its power more quickly.


Does a magnet attract a key?

It depends on the material the key is made of. If the key is made of a ferromagnetic material, such as iron, then yes, a magnet will attract it. If the key is made of a non-magnetic material, such as aluminum or brass, then the magnet will not attract it.

How long does it take for a magnet to lose its magnetism?

The time it takes for a magnet to lose its magnetism can vary depending on factors like the type of magnet and how it is used. In general, permanent magnets can retain their magnetism for many years or even decades if they are not subjected to extreme conditions. However, some magnets may gradually lose their magnetism over time due to factors like exposure to high temperatures or physical damage.


How long does it take for a magnet to lose its power?

The time it takes for a magnet to lose its power can vary depending on factors like the type of magnet and how it is used. Generally, permanent magnets can retain their strength for many years, but can gradually weaken over time due to factors like exposure to high temperatures or physical damage. Electromagnets, on the other hand, can lose their power quickly once the electric current is turned off.

How and what shall you use to make a homemade magnet?

It depends what you want to use it for. You can take something like a needle and stroke it in one directions multiple times over a magnet ( You can use that needle as a compass pointing north with some other help) Something else you can do, is take a long nail and twist some copper wire around it multiple times. If you then take each end of that copper wire and attach it to the respective ends on the battery it will create an electro magnet
