SUMMARY

Aluminum is a diamagnetic material, meaning it does not stop magnetic force but rather exhibits a weak repulsion in the presence of a magnetic field. This was confirmed through experimental evidence, as noted by physicist Richard Feynman. In contrast, Bismuth is repelled by magnetic fields, demonstrating a stronger diamagnetic property. Therefore, aluminum cannot effectively block or stop magnetic forces.

PREREQUISITES
  • Understanding of diamagnetism and its properties
  • Familiarity with basic magnetic concepts
  • Knowledge of materials science, specifically regarding aluminum and bismuth
  • Awareness of experimental physics methods
NEXT STEPS
  • Research the properties of diamagnetic materials
  • Explore the differences between diamagnetic and ferromagnetic materials
  • Study the applications of aluminum in electromagnetic environments
  • Investigate the experimental methods used to demonstrate magnetic properties of materials
USEFUL FOR

Students of physics, materials scientists, and anyone interested in the properties of metals in magnetic fields will benefit from this discussion.

Ok my question is this, can Aluminum (i can't spell) Stop magnetic force?

Nope.

The spelling looks ok to me but I don't know how the Brits spell it but they pronounce it al-u-min'-ium.

Feynman tells us that it has been shown experimentally that aluminum is diamagnetic. So is Bismuth. Aluminum is attracted toward the pointed south pole of a strong electromagnet (direction of ferro magnetic material) while Bismuth is repelled from the south pole.
cheers, Jim
