Either:
James Clerk Maxwell
-His greatest achievement was his demonstration that light is an electromagnetic wave. He originated the concept of electromagnetic radiation.
His field equations, known as Maxwell's equation aided Einstein with the theory of relativity.
OR
André-Marie Ampère
The ampere is the SI unit of electric current named after André-Marie Ampère , a French mathematician/physicist who measured of the amount of electric charge passing a point per unit time (known as an amp).
Electromagnetism was discovered, per se, by James Clark Maxwell. He was the first to say that positive and negative charges were regulated by one force.
Radioactivity was first discovered in 1896 by the French scientist Henri Becquerel.
The relationship between electricity and magnetism was discovered by the scientist Michael Faraday in the 19th century.
None.
James Chadwick
Electromagnetism was discovered by Hans Christian Orsted, a danish scientist in 1820. Whilst preparing for a lecture, he noticed that a compass needle could be moved by the electric current in a battery. Hope that helps!! x

Hans Christian Ørsted discovered the relationship of electric current to magnetism.
Michael Faraday did not invent or discover electromagnetism. After Hans Christian Oersted discovered it he simply studied it more.

He's probably best known for his equations dealing with electromagnetism.
yes, she is a scientist and discovered radiation.
Hans Christian Oersted (1777-1851) of Denmark discovered electromagnetism in 1819.
Hans Oersted discovered Electro- Magnetic Induction in 1820
Michael Faraday, investigating further the earlier discovery of electromagnetism by Dr. Hans Christian Oersted (of Denmark).
in 1894, a Swiss scientist, Alexander Yersin discovered the bacteria that caused it, Yersinia Pestis
