Did Michael Faraday invent magnetism?
No. but he used an electromagnet to make discoveries about electricity.
Does putting a magnet in the water for 60 minutes make the magnet lose its magnetism?
No it wont but if the water is hot then it will lose its magnetism
What happens when you remove the power source from an electromagnet?
It loses it's magnetism, or most of it.
Can the rock magnetite lose its magnetism?
The rock magnetite can only very rarely lose all of its magnetism. It is an important source and tool for magnetism and the testing of equipment in laboratories.
What is affected by a electromagnet?
Other magnets, as well as magnetic substances such as iron, in which magnetism is induced by the external magnetic field.
When is magnetism lost in an electromagnet?
Magnetism is lost in an electromagnet when the electricity is turned off.
What magnet holds a force for a limited time?
An electromagnet will lose most of its magnetism, once the current is turned off.
Did Michael Faraday invent magnetism?
No. but he used an electromagnet to make discoveries about electricity.
What will increasing the electric current to an electromagnet do to its magnetism?
An increasing electric current moving into an electromagnet will become stronger in its magnetism. As the atoms align the increasing magnetism will stop at one point, making the electromagnet as strong as it can be.
What is the synonyms of electromagnet?
Combo of electricity and magnetism
Does putting a magnet in the water for 60 minutes make the magnet lose its magnetism?
No it wont but if the water is hot then it will lose its magnetism
How do make an electromagnet stop working?
An electromagnet is powered by electrical current and that current can be adjusted to different levels of magnetism,Êso if you disable its electrical connection it will not work.
Is electromagnets are natural magnets?
The magnetism of an electromagnet is natural (it comes out of the laws of physics), but the magnetism disappears when the electricity is turned off - it is not a permanent magnetism.
Describe how you think an electromagnet can be used to make a stack of scrapped cars three cars high?
An electromagnet's switched can be turned on, so that it can induce magnetism. Anelectromagnetcaneasilymake a stack of three carsbecausecar body is made a steel. Electromagnet and Steel develop a good power of magnetism.
What advantage does an electromagnet have against a bar magnet?
With an electromagnet, the magnetism can be turned on and off according to the whim or need of the operator.
A permanet magnet will lose magnetism?
over time it will lose its magnetism. It will also lose its magnetism if it is temperature is to high or when it's vibrate too much.
What happens when you remove the power source from an electromagnet?
It loses it's magnetism, or most of it.
