How strong is an electromagnet compared to a permanent magnet?
An electromagnet is typically stronger than a permanent magnet because it can be adjusted by changing the electric current flowing through it. Permanent magnets have a fixed magnetic strength that cannot be easily altered.
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.
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.
Is the magnet in a compass a permanent or electromagnet?
The magnet in a compass is a permanent magnet. It retains its magnetism without the need for an external electrical current.
Which is better a permanent magnet or an electromagnet?
electromagnet

Is a permanent magnet called a hard magnet or a electromagnet?
Perminant magnet
What can you do with an electromagnet that you cannot do with a permanent magnet?
You can control the strength of an electromagnet by adjusting the current flowing through it, which is not possible with a permanent magnet. Additionally, you can turn the electromagnet on and off by controlling the electric current, allowing for greater flexibility in applications such as lifting objects or generating magnetic fields.
Is the magnet in a compass a permanent magnetic or an electromagnet?
PermanentThere is no source of current in a compass, therefore the magnet is a permanent magnet.
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.
Why will an electromagnet be able to pick up more steel cans than a permanent magnet?
An electromagnet is a stronger magnet.

How does heat affect a magnet?
A permanent magnet (i.e. not an electromagnet) will be demagnetised by heating it.
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.
Is the magnet in a compass a permanent or electromagnet?
The magnet in a compass is a permanent magnet. It retains its magnetism without the need for an external electrical current.
How can you make an electromagnet rotate?
To make an electromagnet rotate, you can place it in the proximity of a permanent magnet. When a current flows through the electromagnet, it interacts with the magnetic field of the permanent magnet, causing the electromagnet to rotate. This setup can be used in devices like electric motors and generators.
