What is an Electromagnent?
An Electromagnet is a soft metal core made into a magnet by the passage of an electric current through a coil around it.
How Does It Work?
An electromagnet works because an electric current produces a magnetic field. The magnetic field produced by an electric current forms circles around the electric current.
Who Invented An Electromagnet?
William Sturgeon was the man who invented the Electromagnet in 1825. The first electromagnet was a horseshoe-shaped piece of iron that was wrapped with coil which was wounded in several turns. It was magnetized but when the current stopped the coils became demagnetized.
