Question

what is Quincke's tube?

Answer 1

1. It is the method's apparatus used for determining the magnetic susceptibility of the given solution.
2. It is a U-shaped tube that has two limbs.
3. One limb of the tube has narrow width than the other limb.
4. The liquid in the narrow limb does not change when the level in the winder limb.
5. This method is based on the force experienced by magnetized material in the non-uniform magnetic field.
6. If the liquid is paramagnetic with respect to the surrounding air, the liquid level will rise.
7. If the liquid is diamagnetic, then the liquid level will fall.
8. Magnetic susceptibility is dimensionless proportionality constant.
9. That indicates the degree of magnetization of a material in response to an applied magnetic field.
