​

Answer 1

Answer:

The correct answer will be

(C) the diamagnetic substance weighs maximum in the magnetic field.

Explanation:

First statement -

The diamagnetic substance weighs less in the magnetic field.

This is true because the force acts in the opposing direction so it weighs less.

Second statement -

The paramagnetic substance weighs more in the magnetic field.

This is true because in this case, the magnetic force acts in the same direction resulting in an increase in weight.

Third statement -

The diamagnetic substance weighs maximum in the magnetic field.

This is false because it is contradicting statement 1. Paramagnetic substances should weigh less in the magnetic field.

Fourth statement -

The ferromagnetic substance weighs maximum in the magnetic field.

This is true because the magnetic force acts in the same direction resulting in the maximum weight of the substance.
