Question

A thin light weight rod of diamagnetic substance such as silver is suspended in uniform external magnetic field. It will align itself with its length ______.

पर्याय

• parallel to magnetic field

• perpendicular to magnetic field

• inclined at an angle 45° to magnetic field

• inclined at an angle 120° to magnetic field

Answer 1

A thin light weight rod of diamagnetic substance such as silver is suspended in uniform external magnetic field. It will align itself with its length perpendicular to magnetic field.

Explanation:

When placed in an external magnetic field, diamagnetic substances become weakly magnetized in the opposite direction.

When a dimagnetic substance is suspended freely in a homogeneous magnetic field, 
it becomes perpendicular to the field.
