The original electromagnet was invented by the Englishman William Sturgeon in 1825.
It was much improved by the American Henry in 1830.
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.
The mental center of an electromagnet is called the magnetic pole. It is the point on the electromagnet where the magnetic field is concentrated and strongest.
Yes, quarters can stick to a homemade electromagnet as long as the electromagnet is strong enough to attract the metal in the quarters. The strength of the electromagnet will determine how well it can attract and hold onto the quarters.
The rotating electromagnet in an alternator is called the rotor.
Iron, Nickel, Cobalt
The electromagnet was invented in the year 1850 by william sturgeon :)
British electrician David Sandy invented the electromagnet in 1825 when he was bored.

British scientist William Sturgeon invented the electromagnet in 1824.[7][8] His first electromagnet was a horseshoe-shaped piece of iron that was wrapped with about 18 turns of bare copper wire
The junkyard electromagnet was not invented by a single individual, as electromagnets have been around since the early 19th century. However, the concept of using an electromagnet in a junkyard to lift and move metal debris is often credited to entrepreneurs and inventors in the automotive salvage industry.
An electromagnet is a magnet in which the magnetic field is made by an electrical current. William Sturgeon, an English physicist and inventor, invented the first electromagnets.
