In 1820, ampere made a small experiment at the regular meeting of the Academy of Sciences, which aroused the interest of the scientists at the meeting: hang the spiral tube horizontally, and then electrify the wire. Think about what would happen?

There's a little needle next to it, and it's deflecting

Ampere is a physicist in that country

Andr é Marie amp è (1775-1836), a French physicist, also contributed to mathematics and chemistry. He was born in Lyon on January 22, 1775, into a wealthy family. He showed his mathematical ability when he was young

Examples of the application of research done by physicist ampere in real life

In short, relay, bell, motor. All the electrical appliances based on the principle of electromagnetic induction are their applications. Observe the electrical appliances around you. Most of them have the theory of ampere

Many scientists have contributed to the development of electromagnetism
A. British physicist ampere accurately measured the electric quantity of the elementary charge through the "oil drop experiment". B. Dutch scholar Lorentz proposed the famous molecular circulation hypothesis. C. British physicist Faraday proposed that there is an electric field around the charge, and the interaction between the charges occurs through the electric field. D. Danish physicist Auster first revealed the relationship between electricity and magnetism through experiments

A. Millikan measured the exact value of electron charge through the oil drop experiment. The value of charge of any object is an integral multiple of that of the elementary charge. So a is wrong. B and ampere put forward the hypothesis of molecular current, so B is wrong. C and Faraday, the British physicist, put forward that there is an electric field around the charge, and the interaction between the charges
