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.
An electromagnet its magnetism if the electric current stops flowing?

What happen to a electromagnet if you switch the current off?
When we turn of the current in an electromagnet then electromagnet looses its magnetic property,provided the material used inside the current carrying solenoid is soft iron core. If, the material is steel then after the current is turned the magnetism propety still prevails and hence steel becomes a permanent magnet.
Which of the following statements describes electromagnetism?
Magnetism can create electricity, and electricity can create magnetism.
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.
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
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.
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.
Did Michael Faraday invent magnetism?
No. but he used an electromagnet to make discoveries about electricity.
What happens when you remove the power source from an electromagnet?
It loses it's magnetism, or most of it.
If an electromagnet was free to move how would it move?
Electromagnet is the magnet which is becoming active so long current through the coil flows. If current stops then the magnetism disappears. If a core made up of soft iron is used then magnetism will become more intense but the magnetism exists so long the current flows. Any way electromagnet will behave just like a permanent bar magnet. So electromagnet would set itself along the earth's magnetic meridian.
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.
What would happen if you placed a compass near an electromagnet?
You would not get a true reading any longer. The forces of the electromagnet are greater than the natural magnetism of the Earth.
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.
Why electromagnet is different from a permanent magnet because an electromagnet what?
Mainly in that the electromagnet is NOT permanent. In other words, it can be switched on and off.Another relevant difference is that the electromagnet constantly requires power, at least while it is on.
An electromagnet its magnetism if the electric current stops flowing?
