Paramagnetic

Vedclass · Answer

(B) When a liquid is placed in a non-uniform magnetic field,it experiences a force depending on its magnetic susceptibility. Paramagnetic liquids are attracted towards the stronger part of the magnetic field. Since the meniscus of the liquid rises in the limb when placed between the poles of an electromagnet (where the field is stronger),it indicates that the liquid is attracted to the magnetic field. Therefore,the liquid is paramagnetic.

The meniscus of a liquid contained in one of the limbs of a $U-$tube is placed between the poles of an electromagnet with the meniscus in line with the field. The liquid is seen to rise in the limb by a small amount. This indicates that the liquid is:
