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.

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 is the flow of electromagnets called?
Electromagnets
What are four types of electromagnets?
The four types of electromagnets include solenoid electromagnets, flat-faced electromagnets, cylindrical electromagnets, and horseshoe electromagnets. Each type has unique features and applications depending on their design and magnetic field strength.
Do electromagnets affect glue?
Electromagnets do not affect glue.
Do food processors have electromagnets?
Yes, food processors do have electromagnets.
Are all electromagnets magnetic?
All electromagnets are magnetic when they are turned on.
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.
How do trains levitate?
Electromagnets on the track repel electromagnets on the bottom of the train.
Does an iron box use electromagnets?
no there is no use of electromagnets in iron box
What are 5 facts about electromagnets?
Electromagnets are created by passing an electric current through a coil of wire. They can be turned on and off by controlling the flow of electricity. The strength of an electromagnet can be increased by adding more coils of wire or increasing the current. Electromagnets are used in a wide range of devices, from speakers and electric motors to MRI machines. The polarity of an electromagnet can be reversed by changing the direction of the electric current.
How do cat scans use electromagnets?
CAT Scan does not use electromagnets, its MRI (Magnetic Resonance Imaging) which uses Electromagnets to produce images of the patient's body.
What has the author D J Kroon written?
D. J. Kroon has written: 'Electromagnets' -- subject(s): Electromagnets 'Laboratory magnets' -- subject(s): Electromagnets
What do electromagnets look like?
Electromagnets come in multitudes of shapes and sizes. However, the most common electromagnets have copper wire wrapped around them that are energized when electricity is applied.
