A magnet is an object that is capable of producing a magnetic field. An interesting fact about magnets is that they are used transduce the vibration of strings on an Electric Guitar in order to amplify the sound.

An electromagnet is a coil of electrical wire that is wrapped around a ferromagnetic coil. The discoverer of electromagnetism was Hans Christian Orsted in 1820. Electromagnets have many use, including to lift heavy metal apparatus and MRI machines.

Permanent magnets and electromagnets both hold their magnetism for a long period?
the answer is false Permanent magnets will hold their magnetism for a long period of time. Electromagnets will only remain magnetic as long as current is flowing through them.
How do electromagnets find uses in a vending machine?
Electromagnets are used in vending machines to deciever real coins from fake ones. Electromagnets will sort counterfeit money from real money, because most counterfeit money is an iron alloy. Iron is magnetic and gets pulled by the electromagnet, while real coins are not effected.
Where is the electromagnet the strongest?
The strongest type of electromagnets are superconducting electromagnets. Usually these superconducting electromagnets are immersed in liquid nitrogen or liquid helium to cool them to near absolute zero. === === For non-superconducting electromagnets, the strongest electromagnets would have the greatest ampere turns over a large area. The core of the magnet would be a highly ferromagnetic material, such as iron, or a mixture of a ferrite and a ceramic. Very strong electromagnets used for lifting machinery have both poles on the bottom side which will maximize the magnetic field produced. Non-superconducting electromagnets will saturate and stop producing magnetic fields at about 2 teslas or so. This is the limit of magnetic strength of ordinary electromagnets.
What common alloy is used to make magnets?
Iron is used for electromagnets.
What are 5 facts about electromagnets?
1 a nuke uses electromagnets so does not fall apart they use it to keep the iron shell on and so it does not fall over and does not explode randomly.
What is the flow of electromagnets called?
Electromagnets
Do electromagnets affect glue?
Electromagnets do not affect glue.
How are electromagnets different from magnets?
You can turn electromagnets on and off.
How are electromagnets different from permanent magnet?
You can turn electromagnets on and off.
Do food processors have electromagnets?
Yes, food processors do have electromagnets.
Are all electromagnets magnetic?
All electromagnets are magnetic when they are turned on.
Where use electromagnets?
Inside of electric motors are electromagnets and permanent magnets. In a metal junk yard large electromagnets are used to pick up metal. In MRI's large electromagnets are used for imaging.
What are the electromagnets called that are used at junkyards?
The electromagnets that are used in junkyards are called just that, electromagnets. They are used to sort out different types of metals.
Does an iron box use electromagnets?
no there is no use of electromagnets in iron box
How do trains levitate?
Electromagnets on the track repel electromagnets on the bottom of the train.
How are electromagnets diffrent to either temporary or pemanent magents?
Electromagnets can be turned on and off.
