If a diamagnetic solution is poured into a U-tube and one arm of this U-tube is placed between the poles of a strong magnet, with the meniscus in line with the field, then the level of solution will

View answer and explanation

Correct option: B

Fall

Option B (Fall) is correct because diamagnetic substances are repelled by magnetic fields, causing the liquid level to fall in the region of higher field strength.
