How will a dia , para ferro magnetic material behave when kept in a non uniform external magnetic field ? Give one example of each of these materials.

Explanation

In a non - uniform magnetic field, a diamagnetic substance tends to move slowly from stronger to weaker parts of the field , a paramagnetic substance tends to move slowly from weaker to stronger part of the field, while a ferromagnetic substance moves easily from weaker to stronger parts of the field.
Diamagnetic material : Bismuth
Paramagnetic material : Aluminium
Ferromagnetic material : Iron
