The force required is related to the yield stress of the solid formed by the steel balls. You can make the steel balls behave as a fluid by making a gas flow through them. This creates a fluidised bed. The gas pushes the steel balls apart so the friction between them is removed, and in this state the steel balls will behave like a fluid and the ...

Steel ball bearing in a magnetic field | Physics Forums

Jun 12, 2014· A steel ball bearing is placed to the left of the magnet where it is equidistant from the north and south ends. Consequently, a force pushes the ball to the centre of the magnet. From my knowledge of Fleming's left hand rule and induction, a current needs to be present for forces to occur, however I do not see where the currents are.

Ask a Physicist Answers - Physics Central

Steel is so hard that it barely dents at all and therefore doesn't store any of the collision energy. All the storing and bouncing is up to the ball. Most rubbers are pretty efficient at this job, but not as efficient as steel itself. Such balls just don't rebound as high as a steel ball when you drop them on a steel surface.
