Question

Consider the following statements.
$1$. Au, Ag, Cu, Zn, Sb, Bi, $H_{2}O$ and air are examples of diamagnetic materials.
$2$. Na, Al, Mn, $CaC{l}_2$ and oxygen are examples of paramagnetic materials.
$3$. Fe, Co, Ni and $F{e}_3{O}_4$ are examples of ferromagnetic materials.
Which of the statement(s) given is/are correct?

• A. $1$ only
• B. $2$ only
• C. $2$ and $3$
• D. $1,2$ and $3$

Answer 1

The correct option is D $1,2$ and $3$

Diamagnetic substances are weakly repelled by magnetic field and Au, Ag, Cu, Bi etc are some of the examples.
Paramagnetic substances are weakly attracted by magnetic field and Na, Al, Mn etc are some common examples.
Ferromagnetic substances are strongly attracted by magnetic field and Fe, Co, Ni etc are the examples.
