Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. Who discovered Diamagnetism?1778
2. What is the primary discoverer?Anton Brugmans
3. What is the magnetic susceptibility (χ)?Negative and very small (approx. -10⁻⁵ to -10⁻⁶)
4. Why do some materials push away magnets instead of pulling them?Because all the electrons in those materials are paired, so they don't have a permanent magnetic moment. When a magnetic field is applied, the paired electrons move slightly and create a small magnetic field that pushes back.
5. How did scientists discover diamagnetism?In 1778, Anton Brugmans saw that bismuth was repelled by a magnet. Later, Michael Faraday studied it carefully and showed that all matter has this property.

Lenz's Law: States that an induced current in a conductor opposes the change in magnetic flux that produced it.
Magnetic Susceptibility: A dimensionless quantity that indicates the degree of magnetization of a material in response to an applied magnetic field.
Meissner Effect: The expulsion of a magnetic field from a superconductor during its transition to the superconducting state.
