Practicing Success
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? |
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. |
On heating, ferrimagnetic substances lose ferrimagnetism. |
On heating ferrimagnetic substances changes to paramagnetic substances. |
