Question:

Read the below paragraph and answer the following questions;

Every substance has some magnetic properties associated with it. The origin of these properties lies in the electrons. Each electron in an atom behaves like a tiny magnet. The magnetic strength depends on the number of unpaired electron possessed by the element. On the basis of their magnetic properties, substances can be classified into five categories: (i) paramagnetic (ii) diamagnetic (iii) ferromagnetic (iv) antiferromagnetic and (v) ferrimagnetic.

Which among the following statement is correct?

Options:

H2O is a paramagnetic substance.

For paramagnetic substances, magnetism remains even in the absence of magnetic field.

On heating, ferrimagnetic substances lose ferrimagnetism.

Cr2+ is a ferromagnetic substance.

Correct Answer:

On heating, ferrimagnetic substances lose ferrimagnetism.

Explanation:

On heating ferrimagnetic substances changes to paramagnetic substances.
