SUMMARY

The discussion centers on calculating the force between a permanent magnet and an electromagnet using established electromagnetic principles. The Biot-Savart law is utilized to determine the field strength of both magnets. The key to finding the force acting on them lies in applying the Lorentz force equation, which relates the magnetic fields at the location of each magnet. This approach allows for a precise calculation of the interaction between the two magnetic fields.

PREREQUISITES
  • Understanding of Biot-Savart law
  • Familiarity with Lorentz force equation
  • Knowledge of magnetic field strength concepts
  • Basic principles of electromagnetism
NEXT STEPS
  • Research the application of the Lorentz force in magnetic interactions
  • Study the Biot-Savart law in-depth for various configurations
  • Explore numerical methods for calculating forces between magnets
  • Investigate simulation tools for visualizing magnetic field interactions
USEFUL FOR

Physicists, electrical engineers, and hobbyists involved in electromagnetism and magnetic field calculations will benefit from this discussion.

Could anyone help me with calculating the force between an electromagnet and a permanent magnet?

Using Biot-Savart law I'm able to calculate the field strength of the electromagnet at a respective point, I can also calculate the field strength of the permanent magnet. However, the tricky part seems to be relating the two and establishing the force acting on them when exposed to each others fields at a point.

I've looked online and in books on electromagnetism but can't seem to find an equation.

Thanks.
(Project, certainly not homework)

Please do not open multiple threads for the same topic - I deleted the other one.

If you know the field strength of magnet 1 at the place of magnet 2 (and vice versa), you can use the Lorentz force to calculate the forces between the magnets.
