Understanding Magnetic Force: Formulas and Terminology

Click For Summary
SUMMARY

The discussion focuses on calculating the force between two magnetized objects with magnetic fields B1 and B2. It clarifies that magnetic fields do not exert forces on each other but rather on moving charged particles or magnetized objects. The relevant formula for calculating the force is derived from the total magnetic energy stored in a system, expressed as W = (1/2μ0)∫B2 dVvolume, with the force in the x-direction given by Fx = ∂W/∂x. The terms 'a' and 'volume' are also queried for clarification in the context of magnetic fields.

PREREQUISITES
  • Understanding of magnetic fields and their properties
  • Familiarity with the concept of magnetic energy

this is a very low level question:

I want to calculate the force that it is between two magnetic field .

PLZ give me a formula of it for B1 & B2.
 
Physics news on Phys.org
Magnetic fields don't exert forces on each other. Magnetic fields exert forces on moving charged particles, or on electric currents, or on magnetized objects.
 
I know that but I say my question in bad way.

mainly my question is about the force between two magnetized objects that have magnetic field (B1 & B2).

Suppose the total magnetic energy stored in a system is

W = (1/2μ0)∫B2 dVvolume

Then the force in direction x is given by

Fx = ∂W/∂x

thank you.

PLZ tell me that what 'a' & 'volume' means in a magnetic field?
