when a diamagnetic liquid is poured into a U tube & 1 arm of d U tube is placed btw d 2 poles of a strong magnet with d meniscus along d lines of d field den d level of d liquid in d arm wer magnetic field is applied will a)fall b)rise c)oscillate d)remain unchanged ans given as dat it wud fall can u explain how cud it b plz rates assured

it 'll fall
because diamagnetic materials are repeled by magnetic field

diamagnetism:
Kind of magnetism characteristic of materials that line up at right angles to a nonuniform magnetic field and that partly expel from their interior the magnetic field in which they are placed. In most materials, the magnetic fields of the electrons balance each other and add up to zero. However, when placed in an external magnetic field, the interaction of this field with the electrons induces an internal field in the opposite direction. The substance can then be weakly repelled by magnetic poles. Examples of diamagnetic substances include bismuth, antimony, sodium chloride, gold, and mercury.
so it is repelled
therefore falls

yup
it falls down
if u use paramagnetic substance
the level of liquid rises
