Question

A bar of magnetic substance is placed in a magnetic field with its length making an angle of $30^{\circ}$ with the direction of the magnetic field. How will the bar behave?

• A. It will align itself perpendicular to the magnetic field
• B. It will remain as before
• C. It will align itself parallel to the magnetic field
• D. Its behaviour cannot be predicted

Answer 1

Answer: (A)

It will align itself perpendicular to the magnetic field

Answer 2

The bar of the diamagnetic material aligns itself perpendicular to magnetic field due to the reason that magnetic field lines avoid passing through diamagnetic substances.
