What is one advantage of using electromagnets instead of permanent magnets?
Electromagnets can be turned off and off
How are electromagnets diffrent to either temporary or pemanent magents?
Electromagnets can be turned on and off.
An advantage to using electromagnets is that they?
Can be turned on and off.
What are the advantages of electromagnets against normal magnets?
Electromagnets' magnetism can be manipulated. Electromagnets can be magnetised and demagnetised by passing electric current. Therefore they are used in motors- which works when the coil is magnetised by passing an electric current. It is also used for cranes.
What is a magnet that can be turned on and off called?
Electromagnets have an electric current running through them that enables there conductive power to be strengthened. However, a magnets full conductive power can never be "turned off/on".

Can Permanent magnets be turned on and off?
Electromagnet which uses electric current can be turned on and off.

Can electromagnets be turned off by opening an electric circuit?
True.. Yes, they operate by turning the current on and off

Why are electromagnets used in many electic appliances?
because they can be turned on and off by opening and closing electric circuit.
Why are electromagnets good?
Electromagnets are good because they are easily turned off which allows them to be used in a variety of practical applications. They are often used for picking up large loads of metal.
How are electromagnets different from magnets?
You can turn electromagnets on and off.
How do you turn off an electromagnet?
This is what makes a magnet an electromagnet - the ability to turn it on and off... Anyway, electromagnets can be turned off with either the help of a switch, or just by disconnecting the power supply.
