Electromagnets

Some of you out there may have heard or an electromagnet on a daily basis or may have absolutely no idea what they are. Don't worry though you can learn! An electromagnet is a soft metal core made into a magnet by the passage of electric current through a coil surrounding it. An electromagnet works by an electric current produces a magnetic field. The magnetic field produced by an electric current forms circles around the electric current. William Sturgeon was an English physicist and inventor who made the first electromagnets. The first electromagnet was a horseshoe-shaped piece of iron that was wrapped with a loosely wound coil of several turns. Three examples of electromagnets in a day to day basis are the generator/alternator in a car, a blender in your kitchen, and even a vacuum cleaner you use to clean your carpet once a week!
