Question

What is the relationship between electricity magnetism?

Answer 1

in year 1831 Micheal Faraday illustrated through experiment that electrical current is produced in a closed circuit due to varying magnetic field.eg: working of generator.
in 19th century Henry Oersted illustrated with experiment that current flowing in a wire always gives rise to a magnetic field around it. Example working of electro magnets.

in simple words electromagnetism which means with electricty magnetism can be produced and with magnetism also  electricity can also be produced.
