Which of the following is a diamagnetic substance?

Answer:
Diamagnetic substances are those that create a weak magnetic field in a direction opposite to an externally applied magnetic field. The following are examples of diamagnetic substances:

  1. Bismuth (Bi): Bismuth is a classic example of a diamagnetic material. It has all paired electrons, causing it to repel from an external magnetic field.

  2. Graphite: Graphite is another example of a diamagnetic substance. It contains paired electrons that respond weakly to a magnetic field.

  3. Copper: Copper is also diamagnetic because its electrons fill in a manner that does not allow free electron rotation, resulting in weak repulsion to an applied magnetic field.

  4. Silver: Silver is considered a diamagnetic material due to the magnetic behavior exhibited when subjected to an external magnetic field.

These substances exhibit diamagnetic properties due to the paired electron configuration that results in weak repulsion when exposed to a magnetic field.
