This is Faraday, his work is opposite to oersted and ampere, he discovered that the magnetic feild can induce an electric current. but if the magnetic field does not change there will be no electric current produced in a conductor.
he states also that the absolute value or magnitude of circulation of the electric field around a closed loop is equal to the rate of change of the magnetic, his discovery not only on electromagnetism contributed tot he modern understanding of how magnetic can induced electric power.

He predicted the existance of electromagnetic waves by series of mathematical equations, he explained it by math even he didn't know how to experiment. maxwells's aquations states that the absolute value or magnitude of the circulation of the electric field around a closed loop is equal to the rate ofchange of magnetic field through area of enclosed loop.
Maxwell is known as a "Father of Magnetism" although he didn't perform any experiments has a lasting effect,

Not only providing the existence of the EMA also discovered the radio waves by experimenting a spark gap attached an induction coil and separate spark gap on a receiving antenna. when waves created by the sparks of a coil transmitter were picked up by the receiving antenna, sparks would jump its gap as well. hertz is also known as ''Father of Vibration,"
