Question

Who discovered diamagnetism?

Answer 1

1. By seeing that bismuth was attracted to the magnetic field, Anton Brugmans made the first discovery of diamagnetism in $1778$.
2. However, Michael Faraday later in 1845 showed that material responds to the magnetic field when it is placed in one.
3. The term "diamagnetism" was used to describe this phenomenon, and "diamagnetic material" refers to substances that exhibit this effect.
4. A magnetic field repels diamagnetic materials because it induces an opposing magnetic field in them when it is applied, which produces a repelling force.
5. In contrast, a magnetic field draws paramagnetic and ferromagnetic materials together.
