First electromagnet in the world

First electromagnet in the world

The first electromagnet was created by William Sturgeon who demonstrated it to the Society of Arts on May 23, 1825. It was a horseshoe-shaped lacquered iron rod 30 cm long and 1.3 cm in diameter, on top it was covered with a single layer of insulated copper wire.

The electromagnet was supplied from a galvanic battery (voltaic pile) and could hold 3600 g and significantly surpassed natural magnets of the same mass. It was a brilliant achievement for those times.
