Understanding Magnetic Force: Formulas and Terminology

AI Thread Summary
To calculate the force between two magnetized objects with magnetic fields B1 and B2, it's important to note that magnetic fields do not exert forces on each other directly. Instead, they exert forces on moving charged particles or magnetized objects. The total magnetic energy in a system can be expressed as W = (1/2μ0)∫B2 dVvolume, and the force in the x-direction is given by Fx = ∂W/∂x. The terms 'a' and 'volume' refer to specific parameters in the context of magnetic fields, with 'volume' indicating the spatial extent over which the magnetic field is integrated. Understanding these concepts is crucial for accurately calculating magnetic forces.

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?
 
Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...

Thread 'Why measure the speed of light in one direction?'

It may be shown from the equations of electromagnetism, by James Clerk Maxwell in the 1860’s, that the speed of light in the vacuum of free space is related to electric permittivity (ϵ) and magnetic permeability (μ) by the equation: c=1/√( μ ϵ ) . This value is a constant for the vacuum of free space and is independent of the motion of the observer. It was this fact, in part, that led Albert Einstein to Special Relativity.
