The path of a charged particle in a uniform magnetic field depends on the angle theta between velocity vector and magnetic field, When theta is 0^(@) or 180^(@), F_(m) = 0 hence path of a charged particle will be
linear
. <br> When theta = 90^(@), the magnetic force is perpendicular to velocity at every instant.
What will be the path of a charged particle in a uniform magnetic field when it is moving perpendicular to the field direction?
The magnetic force will act perpendicular to velocity at every instant ,path will be
circle
. Due to change in direction momentum will change but the total energy will remain same.
What will be the path of a charged particle moving in a uniform magnetic field at an angle between 0 to 90 degree?
If angle is less than 90 and greater than zero then it will in
helical path
.
What will be the path of a charged particle moving in a uniform magnetic field at any arbitrary angle?
“It will go
along straight path
in Uniform Magnetic Field.” … The motion of charged particle is same as that of magnetic field i.e angle b/w them is 0°. F= qvBsin0° = 0. Thus no force no deflection and it will continue moving straight.
What is the path of a charged particle in a uniform magnetic field if its velocity is not perpendicular to the magnetic field?
In other words, it is the radius of the circular motion of a charged particle in the presence of a uniform magnetic field. If the velocity is not perpendicular to the magnetic field, then
v is the component of the velocity perpendicular to the field
.
What is the path of a charged particle in a uniform magnetic field?
The Motion of Charged Particle in Electric and Magnetic Field.
F = q(v x B)
. Here, the magnetic force becomes centripetal force due to its direction towards the circular motion of the particle. Hence, if the field and velocity are perpendicular to each other, then the particle takes a circular path.
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.
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.
What is the force that changes the path of a charged particle moving through a magnetic field?
The simplest case occurs when a charged particle moves perpendicular to a uniform B-field, such as shown in Figure 2. (If this takes place in a vacuum, the magnetic field is the dominant factor determining the motion.) Here, the magnetic force supplies the
centripetal force F

.
Can magnetic field change kinetic energy?
One basic feature of magnetism is that, in the vicinity of a magnetic field, a moving charge will experience a force. Interestingly, the force on the charged particle is always perpendicular to the direction it is moving. … Hence magnetic forces do no work on charged particles and
cannot increase their kinetic energy
.
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.
Why does a moving charge experience a force in the magnetic field?
This force on the charged particle is always perpendicular to the direction it is moving. Thus magnetic forces cause charged particles to change their direction of motion, but they do not change the speed of the particle. Explanation: In the presence of a magnetic field, a moving charge will
always experience a force
.
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.
When a magnetic field is applied in a direction perpendicular?
Solution : Since force is
perpendicular to direction of motion
. energy and magnitude of momentum remains constant.
What will be the magnetic field at point O?
HintMagnetic field
due to a straight wire and magnetic field due to a circular loop are opposite to each other. …
