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.

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.
 

1. What is the Magnetic Lorentz Force?

The Magnetic Lorentz Force is a force that acts on a charged particle that is moving in a magnetic field. It is perpendicular to both the direction of motion of the particle and the direction of the magnetic field.

2. How does the Magnetic Lorentz Force affect the motion of a charged particle?

The Magnetic Lorentz Force causes the charged particle to move in a circular or helical path around the magnetic field lines. The particle's speed and direction of motion will also change due to this force.

3. What is the relationship between the strength of the Magnetic Lorentz Force and the strength of the magnetic field?

The strength of the Magnetic Lorentz Force is directly proportional to the strength of the magnetic field. This means that as the magnetic field becomes stronger, the force on the charged particle will also increase.

4. How does the direction of the charged particle's motion affect the direction of the Magnetic Lorentz Force?

The direction of the Magnetic Lorentz Force is always perpendicular to the direction of motion of the charged particle. This means that the force will change direction as the particle moves along its path.

5. What are some real-world applications of the Magnetic Lorentz Force?

The Magnetic Lorentz Force is used in a variety of technologies, such as particle accelerators, electric motors, and magnetic levitation trains. It is also important in understanding the behavior of charged particles in space and in plasma physics.
