Since the magnetic force is perpendicular to the direction of travel, a charged particle follows a curved path in a magnetic field. … The magnetic force is perpendicular to the velocity, so velocity changes in direction but not magnitude. The result is uniform circular motion.
Why does a charged particle moving at right angle to the direction of magnetic field follow a circular path?
Explanation. Because when the charged particles move at right angle to the direction of magnetic field, it experiences force which always acts perpendicular to the velocity. … In other words, the force on the charged particle act as centripetal force and it follows a circular path.
Why is the path of a proton in a magnetic field circular?
You can see that the proton follows a circular path as long as it stays in the magnetic field. This is due to the force it experiences from the magnetic field, which is always pushing it in a direction at right angles to both its direction and the direction of the magnetic field.
Why is the path of a charged particle not a circle when its velocity is not perpendicular to magnetic field?
If a charged particle moves in a region of a uniform magnetic field such that its velocity is not perpendicular to the magnetic field, then the velocity of the particle is split up into two components. … Hence the path of the particle is not a circle; it is helical around the field lines.In what condition does a charged particle moving through a magnetic field follow a circular path?
Answer: if the velocity of charged particle is perpendicular to magnetic field then the particle will move in a circular orbit.
Why does a charged particle moves in a circular path?
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.
Why does not a charged particle moving at right angle?
A charged particle moving at right angle to the direction of the electric field experiences force in the plane of electric filed. … Since the force on the charged particle does not remains always perpendicular to the path, it does not move along with the circular path.
What will be the path of a charged particle moving in a uniform electrostatic field?
