Yes.
Electromagnets turn on when an electrical current is sent through the wiring wrapped round the iron core. It ceases to be magnetised when the current is turned off.

What is one advantage of using electromagnets instead of permanent magnets?
Electromagnets can be turned off and off
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 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 happens if an electromagnets ecectricity is turned off?
The magnetic field dies.

Can Permanent magnets be turned on and off?
Electromagnet which uses electric current 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.
Can electromagnets be turned off by opening an electric circuit?
True.. Yes, they operate by turning the current on and off
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".
Are all electromagnets magnetic?
All electromagnets are magnetic when they are turned on.
Why are electromagnets used in many electic appliances?
because they can be turned on and off by opening and closing electric circuit.
Why is magnet used on wardrobe and fridge doors?
they can close easily and they shut off the electricity when a fire alarm goes off magnets don't work any more and the they can be turned on and off.
