Ampere's Law, December 1972 Popular Electronics - RF Cafe Website

André-Marie Ampère (1775-1836) was a French physicist and mathematician who is considered to be one of the founding fathers of electromagnetism. He made numerous contributions to the study of electricity and magnetism, including the discovery of the basic principles of electromagnetism and the development of the theory of electrodynamics.

Ampère was born in the city of Lyon, France, and showed an early aptitude for mathematics and science. He studied at the École Polytechnique in Paris and later taught mathematics there. During his lifetime, he made important contributions to several fields, including physics, mathematics, chemistry, and astronomy.

One of Ampère's most significant contributions to science was his discovery of the relationship between electricity and magnetism. He discovered that when an electric current flows through a conductor, it creates a magnetic field around the conductor. This discovery led to the development of electromagnetism, which became one of the most important branches of physics.

Ampère also developed a mathematical theory to describe the interaction between electric currents and magnetic fields. This theory, known as Ampère's law, states that the magnetic force between two currents is proportional to the product of the currents and the distance between them. This law is still used today in the design of electrical and electronic devices, such as motors and generators.

In addition to his work on electromagnetism, Ampère also made important contributions to the study of chemistry and astronomy. He discovered the relationship between electricity and chemical reactions, which led to the development of electrochemistry. He also made observations of the sun and planets, and proposed a theory to explain the motions of celestial bodies.

In recognition of his many contributions to science, the standard unit of electrical current, the ampere, was named after him. Today, Ampère's legacy continues to inspire new generations of scientists and engineers, who build upon his work to advance our understanding of electricity and magnetism.

While working on an update to my RF Cafe Espresso Engineering Workbook project to add a couple calculators about FM sidebands (available soon). The good news is that AI provided excellent VBA code to generate a set of Bessel function plots. The bad news is when I asked for a table showing at which modulation indices sidebands 0 (carrier) through 5 vanish, none of the agents got it right. Some were really bad. The AI agents typically explain their reason and method correctly, then go on to produces bad results. Even after pointing out errors, subsequent results are still wrong. I do a lot of AI work and see this often, even with subscribing to professional versions. I ultimately generated the table myself. There is going to be a lot of inaccurate information out there based on unverified AI queries, so beware.
