A small piece of a substance is weakly attracted by a strong magnetic field. The substance is A. Diamagnetic B. Ferromagnetic C. Paramagnetic D. Non-magnetic

The correct answer is A. Diamagnetic.

Diamagnetic materials are weakly repelled by a magnetic field. This is because the electrons in a diamagnetic material are arranged in such a way that they create a magnetic field that opposes the external magnetic field.

Ferromagnetic materials are strongly attracted to a magnetic field. This is because the electrons in a ferromagnetic material are arranged in such a way that they create a magnetic field that is aligned with the external magnetic field.

Paramagnetic materials are weakly attracted to a magnetic field. This is because the electrons in a paramagnetic material are arranged in such a

Non-magnetic materials are not attracted to a magnetic field. This is because the electrons in a non-magnetic material are arranged in such a way that they create a magnetic field that is not aligned with the external magnetic field.
