An electromagnet is made by passing an electric current through a coil of wire, which produces a magnetic field. The strength of the magnetic field can be controlled by adjusting the amount of current flowing through the wire. In contrast, a magnet is a material that produces a magnetic field naturally without the need for an electric current.

What is different about an electromagnet compared to a regular magnet?
An electromagnet is different from a regular magnet because it can be turned on and off by controlling the flow of electricity through it, while a regular magnet is always magnetic.
What is an advantage of using an electromagnet rather than a regular magnet?
A regular magnet, "Earth Magnet", can be very strong, the disadvantage of using them is that you cannot turn off the magnet. Electromagnet uses the electricity of a common battery and can be turned on and off, such as for switches in a circuit board.
Is electromagnet a permanent magnet?
No, an electromagnet is not a permanent magnet. It is a magnet that produces a magnetic field when an electric current is passed through it, and the magnetic field disappears when the current is turned off.
How is a electromagnet diffrent then a permanent magnet?
An electromagnet is a temporary magnet that only produces a magnetic field when an electric current is flowing through it, while a permanent magnet retains its magnetism without needing an external electric current. Additionally, the strength of an electromagnet can be easily adjusted by changing the amount of current flowing through it, while the strength of a permanent magnet is fixed.
How is an electromagnet different from a refrigerator magnet?
An electromagnet is a temporary magnet created by passing an electric current through a coil of wire, while a refrigerator magnet is a permanent magnet that can hold items to a refrigerator or other magnetic surface without needing an electric current. Electromagnets can be turned on and off by controlling the electric current, while refrigerator magnets retain their magnetism without the need for an external power source.
How is an electromagnet different a bar magnet?
a electromagnet is bigger than a bar magnet
What is different about an electromagnet compared to a regular magnet?
An electromagnet is different from a regular magnet because it can be turned on and off by controlling the flow of electricity through it, while a regular magnet is always magnetic.
Which is better a permanent magnet or an electromagnet?
electromagnet
How is a permanentmagnet different from a electromagnet?
a permanent magnet is always magnetic as an electromagnet is only magnetic when it is wound around with wire and energised
Is the worlds biggest magnet a magnet or electromagnet?

Is a permanent magnet called a hard magnet or a electromagnet?
Perminant magnet
What are different words that involve magnets?
Electromagnet Superconducting magnet Ferromagnetic Magnetic needle Magnetic compass magnetic field. Hydro magnet Gyro magnet
What is a magnet made by electric current?
An electromagnet.
Why will an electromagnet be able to pick up more steel cans than a permanent magnet?
An electromagnet is a stronger magnet.
Which type of magnet is created from an electromagnet?
a temporary magnet can be created by an electromagnet but it can also be created by any type of strong magnet
Is a refrigerator magnet electromagnetic?
IT is different because an electromagnet runs with electricity. A refrigiator does not run with electricity.
How is electromagnet different from a regular bar or horseshoe magnet?
It requires a current through a coil of wires.
