∙ 9y agoIn a very real sense, the Earth is an electromagnet. It has an iron core with magnetic fields that operate electrically as the mantle rotates above the core.

What are some true statements for magnets and their poles?
The earth is an electromagnet. It has a north pole and a south pole. Apex: A magnet always has two poles, earth is a elecrtomagnet
When is magnetism lost in an electromagnet?
Magnetism is lost in an electromagnet when the electricity is turned off.
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.
Is electromagnet and electromagnetic waves are the same?
no
What does a electromagnet create?
a magnetic field
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.
What is the source of electromagnet?
An electromagnet is a type of magnet whose magnetic properties stem from electricity. The earth has a lot of electromagnet waves running through it's surface, which come from the polarization of the planet. A more simple electromagnet can be made by wrapping wire around a metal object and connecting the wire to a battery (just be careful).
Earth is a what kind of magnet?
Apparently an electromagnet, if that's what you mean, since the current is believed to be the result of currents flowing in Earth's interior.
What would happen to electronics magnets etc if the earths magnetic poles changed?
Nothing - The polarity of an electromagnet depends on the direction of current flow and you can effect the same change in orientation to the earth's field by moving the electromagnet rather than the earth's field.
What are some true statements for magnets and their poles?
The earth is an electromagnet. It has a north pole and a south pole. Apex: A magnet always has two poles, earth is a elecrtomagnet
Which is better a permanent magnet or an electromagnet?
electromagnet
Strong temporary magnet formed when a current is passed through a coil of wire?
A magnetic field.
An electromagnet becomes storgner when the?
