In fact many mornings I pass a memorial plaque placed on a house, in the center of Copenhagen (Nørregade), saying
“In a house on this spot, the physicist Hans Henrik Ã?rsted discovered electro magnetism in the year 1820”

He was setting up an experiment to use as an educational tool for his students, when he noticed that placing a compass next to a live wire, made the compass needle move. This made him dismiss the class, and the next year he published his findings to all major places learning in Europe.

But they didn’t know that then.
