What else can I help you with?
Which is better a permanent magnet or an electromagnet?
electromagnet
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.
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.
What are the advantages and disadvantage's of an electromagnet?
an electromagnet requires electricity and you will have to pay for it. permanent magnets are always on and you can change the strength of it.
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 magnetic force around the electromagnet is not permanent?
An electromagnet is only live (magnetised) when a current is flowing through the coil.
Why will an electromagnet be able to pick up more steel cans than a permanent magnet?
An electromagnet is a stronger magnet.
Objects that keep their magnetic properties for a long time?
A permanent magnet (in contrast to an electromagnet).
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.
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.
Where is the electromagnet in a maglev train?
the electromagnet is in the track then there are permanent magnets on the very bottom of the train on the part that wraps around the track
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
