What is meant by crossed electric and magnetic fields under what condition a charged particle entering a crossed electric and magnetic fields passes Undeflected?
Moving charges produce a magnetic field. … A Charged particle will get undeflected when an electric field is switched off in a region of crossed electric and magnetic field but if the magnetic field is switched off instead of electric field the particle will have initial acceleration.
What do you mean by cross field?
a kick, pass, or ball that goes from one side of a sports field to another during a game.
What is a cross field in physics?
Crossed fields are created by crossing uniform electric and magnetic fields. … The crossing of the fields was used to deflect electrons with equal and opposite forces.
What is meant by crossed electric and magnetic fields?
The term “crossed electric nd magnetic fields” means that the electric and magnetic fields are perpendicular to each other. The force on a particle in electric and magnetic field is the Lorentz force given as F = q (E + v×B)
How does a charged particle moves in an electric field?
In an electric field a charged particle, or charged object, experiences a force. … If two objects with opposite charges are brought towards each other the force will be attractive, it will pull them towards each other.
What is the movement of electric and magnetic field?
The mutual interaction of electric and magnetic fields produces an electromagnetic field, which is considered as having its own existence in space apart from the charges or currents (a stream of moving charges) with which it may be related.
What do you mean by velocity selector?
A Velocity selector is a region in which we will find uniform electric and magnetic field, in other words, a region where the Electric force acting a charged particle will be equal to the magnetic field force.
Is it possible for a cyclotron to accelerate neutrons?
Neutrons that are not charged are electrically neutral. The cyclotron accelerates charged particles. Thus, neutrons are not accelerated by cyclotrons. … Thus, a cyclotron cannot accelerate neutrons as they are not charged.
