Magnetic Lorentz Force: Questions & Answers

Click For Summary
The Magnetic Lorentz force acts on charged particles in a magnetic field, but it does not induce current in a uniform magnetic field due to the lack of a changing magnetic field. Electromagnetic induction, as defined by Maxwell's equations, requires a changing magnetic field to produce electromotive force. The Lorentz force equation, F=q(v*B), is applicable in any inertial frame of reference, meaning the motion of charged particles can be analyzed relative to any inertial observer. Current can indeed be induced in conductors moving through a uniform magnetic field, as demonstrated by Hall probes. Understanding these principles clarifies the relationship between motion, magnetic fields, and induced currents.

Magnetic Lorentz force is the force experienced by any charged particle moving in a magnetic field.i want to clarify some doubts regarding this topic of Magnetic Lorentz force.some of them are:
1. Is it the Lorentz force that is actually responsible for the phenomenon of electromagnetic induction.if yes..they why does current is not induced while moving in uniform magnetic field.
2.Lorentz force is given as F=q(v*B). since all motion is relative ,what should be the frame of reference of the motion that we should consider in the motion of the charged particle.what is the motion of charged particle relative to..
PLEASE give an answer to these humble doubts of this beginner ...

It is relative to any inertial frame. The same equations work in any inertial frame.
 
thank you sir. can you give me an answer for my first question..

What do you mean by this? Wiki states "Electromagnetic or magnetic induction is the production of an electromotive force (i.e., voltage) across an electrical conductor in a changing magnetic field". So the third Maxwell's law:

##\vec{\nabla}\times\vec{E}=-\partial_t\vec{B}##

is responsible for induction. You probably want to talk about motion of charge carriers. Then you need to specify which charge carriers you mean. Free-electrons in vacuum?

Also, about current being induced as a result of motion in magnetic field. What about Hall probes?

Current is induced in a conductor moving in a uniform magnetic field.
 

Thread 'What determines if wave components are independent vs coherent?'

I'm working through something and want to make sure I understand the physics. In a system with three wave components at 120° phase separation, the total energy calculation depends on how we treat them: If coherent (add amplitudes first, then square): E = (A₁ + A₂ + A₃)² = 0 If independent (square each, then add): E = A₁² + A₂² + A₃² = 3/2 = constant In three-phase electrical systems, we treat the phases as independent — total power is sum of individual powers. In light interference...
