A bar of magnetic substance is placed in a magnetic field with its length making an angle of 30° with the direction of the magnetic field. How will the bar behave?

Question

A bar of magnetic substance is placed in a magnetic field with its length making an angle of 30° 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

Tardigrade Admin · Accepted Answer

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.

Q. A bar of magnetic substance is placed in a magnetic field with its length making an angle of 30∘ with the direction of the magnetic field. How will the bar behave?

It will align itself perpendicular to the magnetic field

It will remain as before

It will align itself parallel to the magnetic field

Its behaviour cannot be predicted

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.

Q. A bar of magnetic substance is placed in a magnetic field with its length making an angle of $3 0^{\circ}$ with the direction of the magnetic field. How will the bar behave?
