every time electricity passes through a wire, it gives off an electric current. this is the basis of an electromagnet. if you add coils to the wire, there will be more current in a smaller space this will make it stronger. you can also make it stronger by:
- putting more current through the wire
- putting a iron core through the wire
electromagnets are found in bells, scrap heap cranes, circuit breakers and much more. the advantage of electromagnets is that they can be turned on and off.
What else can I help you with?
Which is better a permanent magnet or an electromagnet?
electromagnet
What does an electromagnet operator do to release metal attached to the electromagnet?
An electromagnet operator can release metal attached to the electromagnet by turning off the electric current flowing through the electromagnet coils. This de-energizes the electromagnet, causing the magnetic field to dissipate and the metal object to fall off.

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.
What is an example of a sentence using the word electromagnet?
Electromagnets are widely used now. Instead of traditional magnets.
Who built the first electromagnet?
Linc Robinson built the first electromagnet.
When was the electromagnet invented?
The electromagnet was invented in the year 1850 by william sturgeon :)
What is the difference between electromagnetism and electromagnet?
electromagnetism is the force an electromagnet is the object
An advantage of an electromagnet (in contrast to a bar magnet) is?
An electromagnet can be turned on and off.
