Magnetic field could only affect moving charges?

AI Thread Summary
The discussion centers on the effects of magnetic fields on moving charges, specifically highlighting that a current-carrying wire experiences force due to the Biot-Savart law. It notes that a current-carrying loop in a magnetic field can experience torque, described by the equation τ = M*B, emphasizing that movement of charge is essential in both scenarios. The conversation also touches on the complexity of magnets, explaining that while electrons typically orbit randomly, in permanent ferromagnets, they align in the same direction. This alignment leads to the magnetic force experienced, which is fundamentally due to the movement of electrons, despite the apparent stability of atoms. Overall, the interaction between moving charges and magnetic fields is a key aspect of magnetism.

no other thing is under effect of B ? srry .i m not good in eng , hope u seniors can understd my q. thanks lot..

A current carrying wire can experience a force given by Biot-Savart law.
A current carrying loop under magnetic field can experience torque which comes under magnetic moment.
$$\tau = M*B$$
But even then in both cases there is a movement of charge(current).
 
Yes.
Incase youre wondering, what we normally consider a "magnet" is a little complicated
Normally electrons orbit around the nucleus in random configurations, while a permanent ferromagnet has electrons all orbitting around the same axis.
Essentially the force we normally experience as magnetism is the interaction between the electrons, that are moving(even though the atoms appear stationary)

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...
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.
