Andre Marie Ampere tried to analyze each experiment in advance and had success. He developed a love for mathematics and presented his mathematical expert experiences in electricity and magnetism along with expert ideas in many fields. In 1825, Ampere compiled his research into a mathematical formula that is now known as Ampere’s law. Ampere’s theory not only clarifies previously understood electromagnetic concepts, but it also makes some unexpected predictions. Ampere was born on January 22, 1775, in Polemieux, a town close to Lyon, France, into a middle-class merchant family. Ampere studied advanced mathematics at the age of 12 due to his exceptional aptitude in chemistry and mathematics. He rose to prominence as one of France’s top mathematicians by the age of 18. Ampere, who lost his father during the French Revolution, received his education from the country’s top teachers. The young Ampere experienced a depressive episode as a result of this incident. He couldn’t concentrate on math, physics, or chemistry again for nearly a year, and he never went back to school.

In 1799, he got married and moved to Lyon to work as a teacher at the Ecole Centraletie. Despite his desire to spend little time learning, he began to give lectures here in order to lay the groundwork for his research. When his wife passed away in 1804 after a few happy years in Lyon, he made his home in Paris. He became well-known as a physics and mathematician in science when he was 34.

At the Paris Polytechnic School, he taught mathematics and mechanics. He began his study of electromagnetism, which he called electrodynamics, here. Ampere’s scientific career changed on September 11, 1820, when Oersted found out about his observations. Ampere started to look into whether the electric currents flowing through the two wires had any impact on one another after realizing the significance of this occurrence. He gave the French Academy of Sciences the findings of his study on this topic.

He claimed that a force perpendicular to the direction of the current is applied by two parallel wires with current flowing through the ampere. Wires that have the same direction of current attract one another, while those with the opposite current repel one another. He also demonstrated how the right-hand rule could be used to determine the magnet’s deflection direction, which Oersted had previously observed. Additionally, it demonstrated how current moves from positive to negative. In an experiment carried out by two different scientists, an iron bar would turn into a magnet if current was run through an insulated conductive wire wound on it. Ampere conducted experiments on the topic and discovered that a coil through which current was passed exhibited magnetism.

Michael Faraday and Joseph Henry made the discovery of electromagnetic induction. Ampere spent days working with chalk and an eraser in front of the blackboard in his laboratory, attempting to write a mathematical equation to explain his observations. Until he realized that he had made plus and minus errors somewhere along the way, he had given up on his efforts. By omitting the minus sign, he created the fundamental ampere equation. When describing his invention as one of the pinnacles of science, Maxwell used the Newtonian definition of electricity for an ampere. The name “Ampere” is given to the unit of current in his honor.
