When a charged particle moves through a magnetic field perpendicular to its direction then?

When a charged particle moves through a magnetic field perpendicular to its direction. Then. When a charge particle perpendicularly enters a magnetic field to the direction, the path of the motion is circular. In circular motion, the direction of velocity changes at every point (the magnitude remains constant).

When an alpha particle at rest is placed in the magnetic field its direction of force?

1. A particle will experience a force in a magnetic field only if it is moving. Thus the alpha particle will not experience any force when placed at rest in the field.

When an electron enter perpendicular to the magnetic field then what is its trajectory?

When a charged particle enters a magnetic field perpendicularly, it moves on a circular path. The required centripetal force is provided by magnetic force.

What happens when a charged particle moves in a magnetic field?

A charged particle experiences a force when moving through a magnetic field. 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.

When a charged particle moves perpendicular to magnetic field and its kinetic energy and momentum get affected?

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 an alpha particle moves in the magnetic field parallel to the field lines?

A particle will experience a force in a magnetic field only if it is moving. Thus the alpha particle will not experience any force when placed at rest in the field. 2. Yes, the particle will experience a force when moves parallel to the magnetic field lines.

What is the force on the alpha particle?

Alpha particles are extremely stable particles, having a binding energy of about 28.8 MeV. The protons and neutrons are held together in a very stable configuration by the strong nuclear force.

When electron and proton enter a magnetic field?

An electron and a proton enter a magnetic field perpendicularly, both have same kinetic energy.

When an electron and a proton enter in a magnetic field which one path is more curved?

We know that protons have larger mass than an electron. Therefore, the radius of the path of the proton will be more, making it less curved.

When a charged particle moves through a magnetic field perpendicular to it the quantities which remains unchanged are?

Both linear momentum and kinetic energy of the particle are constant.

How do alpha particles and a proton enter the magnetic field?

A proton and an alpha particle enter the same magnetic field which is perpendicular to their velocity and have the same kinetic energy. Given, mα​=4mp​

How does a negatively charged particle move in a magnetic field?

A negatively charged particle moves in the plane of the paper in a region where the magnetic field is perpendicular to the paper (represented by the small ’s—like the tails of arrows). The magnetic force is perpendicular to the velocity, so velocity changes in direction but not magnitude. The result is uniform circular motion.

What happens when a charged particle travels in a helical path?

While the charged particle travels in a helical path, it may enter a region where the magnetic field is not uniform. In particular, suppose a particle travels from a region of strong magnetic field to a region of weaker field, then back to a region of stronger field. The particle may reflect back before entering the stronger magnetic field region.

Why is magnetic force perpendicular to the direction of motion?

Another way to look at this is that the magnetic force is always perpendicular to velocity, so that it does no work on the charged particle. The particle’s kinetic energy and speed thus remain constant. The direction of motion is affected but not the speed.
