The susceptibility of a magnetic material is 2 . 6 × 10 - 5 . Identify the type of magnetic material and state its two properties.

The material having positive and small susceptibility is paramagnetic material. Properties They have tendency to move from a region of weak magnetic field to string magnetic field, i.e. they get weakly attracted to a magnet. When a paramagnetic material is placed in an external field the field lines get concentrated inside the material and the fields inside is enhanced.
