Abstract
Liquid sensing apparatuses and liquid sensing methods are described. In some embodiments, a liquid sensing apparatus includes a magnetic element; a source magnetic field, which produces on the magnetic element a magnetic force with a component that opposes a gravitational force on the magnetic element; and a structure configured to prevent rotation of the magnetic moment of the magnetic element relative to the magnetic field, e.g., so that the magnetic force remains greater than the gravitational force. The apparatus is capable of sensing the level of a liquid using a combination of magnetic force and buoyancy force.
