Question

If a diamagnetic material is placed in a magnetic field,the flux density inside the material compared to that outside will be:

• A. Slightly less
• B. Slightly more
• C. Very much more
• D. Same

Answer 1

The correct option is A Slightly less

Given: $A$ $diamagnetic$ $material$ $in$ $magnetic$ $field$

Solution: $Diamagnetic$ $material$ has a property which is

mentioned below in bold letters:-

Magnetic field lines inside a Diamagnetic materials gets

repelled due to which magnetic field intensity gets reduced

inside in comparison of outside the material.

and we all know that,

$magneticfluxdensity,$$\varphi$ $\propto$ $B$ $\left(magneticfiledintensity\right)$

So, as $B$ decreases $\varphi$ also decreases.

hence, inside material $\varphi$ is slightly less then in comparison to

outside the material.

The correct opt: A
