Advantage of using electromagnet in an electric motor rather than a permanent magnet?
convert electrical energy to energy of motion...! the usage of an electromagnet allows us to control the flow of electrons to the electric rotor,thereby allowing us to control the working of the rotor,whereas with a permanent magnet there will be a continuous supply of energy which can be stopped only if the magnet is damaged or heated.
Is the magnet in a compass a permanent magnet or a electromagnet?
It is a permanent magnet. Electromagnets(as the name suggests) requires an electric source to become a magnet, when the power source is turned off it will not function as a magnet.
What is an advantage of using an electromagnet over a permanent magnet?
The advantage of an elecromagnet is that you can turn it on and off with a simple switch. So for example if you want to pick up a scrap car with a crane/electromagnet and move it, you can turn the electromagnet off when you want to release the car. You could not do the with a permanent magnet obviously.
How is a electromagnet diffrent then a permanent magnet?
By definition an electromagnet is only working when it has a supply of electricity, a Permanent Magnet is always a magnet
Is electromagnet a permanent magnet?
no

Is not a permanent magnet?
An electromagnet is a magnet while an electric current is running through the coil. Turn off the current and it is no longer magnetised, and is, therefore, not a permanent magnet.

How can you find out if a magnet is permanent or not?
Look to see if it's got a coil connected to an electric power source or not. If it does, it's an electromagnet, if not, it's a permanent magnet.

Which is better a permanent magnet or an electromagnet?
electromagnet
Is electromagnet a permanent magnet?
no
What is an electromgnet?
An electromagnet is a magnet that runs on electricity. Unlike a permanent magnet, the strength of an electromagnet can easily be changed by changing the amount of electric current that flows through it. The poles of an electromagnet can even be reversed by reversing the flow of electricity.
Is a permanent magnet called a hard magnet or a electromagnet?
Perminant magnet
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.
What is a magnet made by electric current?
An electromagnet.
