Question

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

Options

G1 Physics · Accepted Answer

A ferromagnetic liquid is strongly attracted toward the region of larger B. Therefore the liquid level rises in the arm between the pole pieces. Hence A.
