A ball of superconducting material is dipped in liquid nitrogen placed near a bar magnet.
In which direction will it move?

A ball of superconducting material is dipped in liquid nitrogen placed near a bar magnet. What will be the direction of its magnetic moment?

Direction. In the follwing questions, a statement of assertion is followed by a statement of reason. While answering a question, you are required to choose the correct are out of the given four responses and mark it as (A). If both assertion and reason are true and reason is the correct explanation of the assertion, (B) if both assertion and reason are true but reason is not correct explanation of the assertion. (C) if asssertion is true, but reason if false, (D) if both assertion and reason are false Assertion : A disc-shaped magnet is leviated above a superconducting material that has been cooled by liquid nitrogen. Reason : Supersonductors repel a magnet.

A bar of diamagnetic material 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?

Two similar bars made from two different materials P and Q are placed one by one in a non-uniform magnetic field. It is observed that bar P tends to move from the weak to the strong field region and d. What is the nature of the magnetic materials for making these two bars? Show with the help of a diagram, the behaviour of the field lines due to an external magneic field near each of these two bars.

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

A diamagnetic material in a magnetic field moves

A short bar magnet placed in a horizontal plane has its axis aligned along the magnetic north-south direction. Null points are found on the axis of the magnet at 14 cm from the center of the magnet. The earth's magnetic field at the place is 0.36 G and the angle of dip is zero. If the bar magnet is turned around by 180^@ , where will the new null points be located?

The susceptibility of a magnetic material is 0.085. Identify the magnetic type of the material. A speciman of this material is placed in a uniform magnetic field. Draw the modified field pattern.
