Linc Robinson built the first electromagnet.
The first electromagnet was built by William Sturgeon in 1825. Sturgeon discovered that wrapping an insulated wire around a horseshoe-shaped iron core and passing an electric current through the wire created a magnetic field. This invention laid the foundation for the development of various electromagnetic devices and technologies.
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
A copper wire was wrapped around an iron bar to create the first electromagnet.

The comon bar magnet has two poles, and the electromagnet can be turned on and off also the electromagnet uses electricity to create a magnetic field in the first place. so the difference is normal magnet cant be turned on and off but the electromagnet can. does that answer ur question?
yo bro no body cares oh
The first electromagnet was invented in 1825.
