The magnetism acquired by a magnetic material as long as it is in contact with a magnet

The magnetism of a bar magnet is due to

Ferromagnetic material and non-magnetic material

All metals are magnetic materials.

The intensity of magnetisation of a magnetic material is l . Now material is the cut such that volume of the material is halved, then new intensity of magnetization is

Are keepers magnetic or non-magnetic materials?

A diamagnetic material in a magnetic field moves

A diamagnetic material in a magnetic field moves

The relative magnetic permeability of a magnetic material is 800. Identify the nature of magnetic material and state its two properties.

How does the intensity of magnetization of a paramagnetic material vary with increasing applied magnetic field?

Fig. shows a bar magnet placed on the table top with its north pole pointing towards south. The arrow shows the north-south direction. There are no other magnets or magnetic material nearby. Insert two magnetic field lines on either side of the magnet using arrow head to show the direction of each field line.
