GEOLOGY

Detailed explanation-1: -Ampere created an equation to show this relationship, called Ampere’s Law. He also proposed the existence of a electrodynamic molecule involved in electricity and magnetism. That particle was discovered later and called an electron.

Detailed explanation-2: -He formulated a law of electromagnetism, called Ampère’s law, that describes the magnetic force between two electric currents. An instrument he devised to measure the flow of electricity was later refined as the galvanometer.

Detailed explanation-3: -Until electromagnetism was discovered, scientists thought that electricity and magnetism were unrelated. A Danish scientist named Hans Christian Oersted changed all that. He discovered that electric current in a wire can deflect a magnetized compass needle that means electric current creates a magnetic field.

Detailed explanation-4: -André-Marie Ampère (1775-1836) – Although he was not the first person to observe a connection between electricity and magnetism, André-Marie Ampère was the first scientist to attempt to theoretically explain and mathematically describe the phenomenon.
