Why is the speed of a particle not affected by the 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 direction of motion is affected but not the speed.
Can a magnetic field change the speed of a charged particle?
One basic feature of magnetism is that, in the vicinity of a magnetic field, a moving charge will experience a force. Thus magnetic forces cause charged particles to change their direction of motion, but they do not change the speed of the particle.
Can the magnetic force speed up or slow down a charged particle?
Magnetic force is always perpendicular to velocity. Therefore, the magnetic force cannot change give or take kinetic energy from the object so the object cannot speed up or slow down.
Why does the magnetic force have no effect on the magnitude of velocity of a charged particle?
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.
Why does the magnetic force change when you add more magnets?
By adding one magnet on to the other, e.g. stacking, the stacked magnets will work as one bigger magnet and will exert a greater magnetic performance. As more magnets are stacked together, the strength will increase until the length of the stack is equal to the diameter.
On what factors the force experienced by a charged particle moving in a magnetic field depends?
The force acting on the electrically charged particles in a magnetic field depends on the magnitude of the charge the velocity of the particle and its strength.
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.
