The charged particle moving in a uniform magnetic field with initial velocity perpendicular to the field follows
a circular path
. The force exerted on the charged particle by the magnetic field provides centripetal force
What is the path of charged particle moving in a uniform magnetic field?
If the field is in a vacuum, the magnetic field is the dominant factor determining the motion. Since the magnetic force is perpendicular to the direction of travel, a charged particle follows
a curved path
in a magnetic field. The particle continues to follow this curved path until it forms a complete circle.
What will be the path of a charged particle moving in a uniform magnetic field at any arbitrary acute angle?
“It will
go along straight path
in Uniform Magnetic Field.” Explanation: It is beacuse no deflecting force is acting on charged particle to divert its path. The motion of charged particle is same as that of magnetic field i.e angle b/w them is 0°.
What will be the path of a charged particle entering in a uniform magnetic field explain how does velocity selector work?
In a velocity selector, charged particles
must move at a speed of v=EB v = E B in
order to pass through the equipment. … An uniform magnetic field throughout the space between the two charged plates. The uniform magnetic field can be directed inwards (into the paper) or outwards (out of the paper).
What will be the path of a charged particle moving in a uniform electrostatic field?
The charged particle will experience electrostatic force along the direction of field and will continue to move perpendicular to the field.So the path is
superposition of two straight line paths
,which is parabola.
What will be the shape of path if V is parallel to be?
If the velocity v of the charged particle has a component parallel to the magnetic field B , instead of a circle, the resulting trajectory will be
a helical path
, as shown in figure. Because the velocity of the particle has a non-zero component along the direction of magnetic field B.
Why does the path of the charged particle Bend?
The path of the charged particle bends
because the particle is repelled by the negatively charged plate and attracted to the positively charged plate
. … The greater the magnitude of the charges, the greater the electrostatic repulsion or attraction. As the charge on the plates is increased, the bending will increase.
When any moving charge enters in a magnetic field perpendicularly then its path will be?
When a charged particle enters a magnetic field at a direction perpendicular to the direction of motion, the path of the motion is
circular
. In circular motion the direction of velocity changes at every point (the magnitude remains constant). Therefore, the tangential momentum will change at every point.
When a charged particle enters in the direction of a uniform magnetic field then it moves on a straight path without deviation?
then it moves on a straight path. without deviation. Reason:Magnetic force on a. charged particle
is zero
, when.
When an electron enters a uniform magnetic field at an acute angle its path will be?
An electron enters a uniform magnetic field with a path perpendicular to the field lines and moves in a circular path of radius R. A positron (same mass of an electron but opposite charge) enters the same magnetic field in a path perpendicular to the field with four times the kinetic energy.
How do moving charges create magnetic field?
As Ampere suggested, a magnetic field is produced whenever an electrical charge is in motion.
The spinning and orbiting of the nucleus of an atom
produces a magnetic field as does electrical current flowing through a wire. The direction of the spin and orbit determine the direction of the magnetic field.
What happens to the domain in a ferromagnetic material in the presence of external magnetic field?
The magnetic fields produced by the individual atoms therefore cancel each other. … When a piece of ferromagnetic material is placed into an external magnetic field, two things happen.
The spins in each domain shift so that the magnetic moments of the electrons become more aligned with the direction of the field
.
Can a uniform magnetic field be used to speed up a charged particle?
A magnetic field cannot change the speed of a charged particle
. It can change the particle’s direction of motion, so it can change the particle’s velocity, and in that way cause the particle to accelerate.
What is the path of a charged particle moving in a uniform electrostatic field with initial velocity?
(ii) When a charged particle moves perpendicular to both electric and magnetic fields, then due to electric field, the charged particle describes
a parabolic path
the due to magnetic field, it will describe a circular path. As a result of it, the particle will follow a resultant path in electric and magnetic fields.
What is the path of a charged particle in a electric field?
The angle dependence of the magnetic field also causes charged particles to move perpendicular to the magnetic field lines in a circular or helical fashion, while a particle in an electric field will move in
a straight line along an electric field line
.
Why cyclotron is not suitable to accelerate electrons?
Electrons can not be accelerated by cyclotrons
because the mass of electron is very small and a small increase in energy of electron makes the electrons move with very high speed
. … Cyclotron can not be used for accelerating uncharged particle like neutrons.
