SUMMARY

The discussion centers on calculating the pull force of magnets using specific parameters such as shape, thickness, diameter, and Br value in gauss. A teacher seeks to develop a lab experiment utilizing Hooke's Law to measure the force required to separate a magnet from a metal plate, incorporating layers of plastic to observe changes in force. The relevant equation for these calculations is referenced in post #22 of the linked Physics Forums thread. This formula is essential for accurately determining magnetic pull force in educational settings.

PREREQUISITES
  • Understanding of Hooke's Law and its application in measuring force
  • Familiarity with magnetic properties, specifically Br value in gauss
  • Knowledge of magnet geometry, including shape, thickness, and diameter
  • Basic skills in experimental design for educational labs
NEXT STEPS
  • Research the equation for calculating magnetic pull force as discussed in post #22 of the Physics Forums thread
  • Explore the principles of Hooke's Law and its practical applications in experiments
  • Investigate the effects of different materials (e.g., plastic) on magnetic force measurements
  • Learn about the various shapes of magnets and how they influence pull force calculations
USEFUL FOR

Teachers developing physics labs, students studying magnetism, and educators interested in hands-on experiments involving magnetic forces.

I am a teacher and am in the process of developing labs dealing with magnets. I have seen calculators on the internet that can calculate the pull force in pounds for a magnet when provided the shape of magnet, thickness, diameter and Br value in gauss. I have failed to find the equation used for such calculations, can you point me in a direction where I may find such equations?

I would like to develop a lab where my students can use a Hooks Law apparatus and measure the force needed to separate a magnet from a plate of metal. And then place layers of plastic between the magnet and metal and measure the force again.

Any help would be great.
