Abstract

In the floating situation, gravitational and magnetic forces acting downward on the metal tea ball are in equilibrium with the buoyant force acting upward. As the buoyant force is switched off, the magnets attract the tea ball and very quickly bring it to the bottom of the container (Fig. Absence of buoyant force when a fluid and submerged object are in free fall together can be demonstrated in two ways.
