An electromagnet uses an electric current flowing through a wire. That current creates a magnetic field around the wire and is the basis for Ampereâ??s circuital law. In electromagnet can be amplified by both increasing the charge, and also wrapping the wire around a soft metal like iron.

∙ 14y agoWhen a magnet is moved near an electrical conductor (usually a coil of wire), it excites electrons in the conductor. This happens because the magnet is polarized, meaning one side has a negative and one a positive charge, and this charge attracts or repels electrons in the conductor. The motion of the electrons is electricity.

When is magnetism lost in an electromagnet?
Magnetism is lost in an electromagnet when the electricity is turned off.
What is the difference between magnetism and electricity?
The difference between electricity and magnetism is that you must be in the same frame of reference as the electric field to experience electricity, because all that magnetism is, is electricity moving relative to you.Although they are two different forms of energy, you can use magnetism to create electricity and you can use magnetism to create electricity.Electricity is the flow of energy or current through a metallic substance. Magnetism is the attraction of the metallic molecules in a solid or substance.
Are electricity and magnetism the same thing?
Electricity and magnetism are similar but yet different. They are both able to make a form of each other. If electricity charges are pulled at a great force they will be able to create a type of magnetic force. Magnets are able to produce forms of electricity when their pulls are changed.
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.
What are two advantages of a electro magnet over natural magnet?
A permanent magnet is always on; there isn't any way to turn it off. An electromagnet can be controlled; you can turn it on or off, or change the amount of magnetism by varying the current passing through the coils.
When is magnetism lost in an electromagnet?
Magnetism is lost in an electromagnet when the electricity is turned off.
What is the synonyms of electromagnet?
Combo of electricity and magnetism
What does electricity produce?
magnetism
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.
Did Michael Faraday invent magnetism?
No. but he used an electromagnet to make discoveries about electricity.
Does electromagnet produce electricity or use electricity?
It doesn produce electricity. It uses electricity and shows magnetic properties.
What relationship does electricity and magnetism have with each other?
they both produce electricity.
Can you produce electricity even without magnetism?
yes we can produce electricity without magnetism by using semiconductor for example photo diode is used in solar cells.
Who demonstrated that magnetism can produce electricity?
Micheal Farraday
How do electrons produce elctricity?
The movement of free electrons is' electricity. So electrons can not produce electricity; but it is produced by magnetism.
How do electricity and magnetism produce movement?
Well, electricity and magnetism are not the same. Electricity is the movement of free electrons in a material, while magnetism is a field in space that has direction and magnitude. In fact, you can create electricity with magnetism and motion. and you can make magnetism with electricity and motion. And for your knowledge you can create motion with electricity and magnetism. It is a law of nature, like gravity.
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.
