All eyes converged on the podium as everyone was eager to see what kind of results could make the normally calm and composed Mr. Michael Faraday so delighted.
Faraday said with a smile, "I believe many in the audience are aware that the world has been researching electricity and magnetism for many years now.
But in the earliest days, researchers thought these were two separate disciplines."
However, the merchants disagreed with us.
Because in the 18th century, a London merchant made a startling discovery: his box of iron spoons had become surprisingly magnetic after being struck by lightning.
This disagreement between scientists and merchants wasn't resolved until 1820, the year when Danish scientist Hans Oersted conducted an experiment.
He placed a wire parallel to a magnetic needle, and the moment he switched on the electric current, he was surprised to find that the needle jerked.
