Inclined Plane Experiment: Iron Ball Attraction and Stopping Behavior

Click For Summary
SUMMARY

The discussion focuses on the behavior of iron balls rolling down an inclined plane towards a fixed magnet. When a single iron ball approaches the magnet, it becomes magnetized and is attracted. However, when two iron balls are present, they stop midway down the plane, likely due to mutual attraction and friction between them. The participants explore the dynamics of magnetic attraction and friction, questioning whether the friction is sufficient to counteract the magnetic forces at play.

PREREQUISITES
  • Understanding of basic physics concepts such as magnetism and friction.
  • Familiarity with inclined plane mechanics.
  • Knowledge of magnetic properties of iron.
  • Basic principles of motion and forces.
NEXT STEPS
  • Research the principles of magnetic attraction and how they affect motion.
  • Study the effects of friction on rolling objects on inclined planes.
  • Explore experiments involving multiple magnetic objects and their interactions.
  • Learn about the properties of materials that influence magnetization.
USEFUL FOR

Physics students, educators, and hobbyists interested in experimental mechanics and magnetism will benefit from this discussion.

When an iron ball is allow to roll down the inclined plane such that magnet is fixed at the bottom of plane then rolling ball is attracted towards the magnet. But if two iron balls all allow to roll down then they stop in between on plane. Why
 
Physics news on Phys.org
Shot in the dark, but perhaps the first ball is magnetized by the magnet as it approaches, which then attracts the second one towards it, and the friction generated between them (plus the magnetic force?) causes them to stop rolling.
 
I agree with your answer. But is that friction enough to avoid attraction on inclined plane

What do you mean by "avoid attraction on inclined plane"?
 
Attraction towards the magnet
