What is the force experienced by a moving charge in a magnetic field?
Click to flip
The force is called the Lorentz force and is given by F = q(v × B).
Click to flip
What are the factors that influence the magnitude of force on a moving charge?
Click to flip
The magnitude is influenced by the charge magnitude, velocity of the charge, and the strength of the magnetic field.
Click to flip
In which direction does the force act on a moving charge in a magnetic field?
Click to flip
It acts perpendicular to both the velocity of the charge and the magnetic field.
Click to flip
What is the formula for calculating magnetic force on a moving charge?
Click to flip
F = q(v × B), where F is the force, q is the charge, v is the velocity, and B is the magnetic field.
Click to flip
What happens to the path of a charge moving perpendicular to a uniform magnetic field?
Click to flip
The charge moves in a circular path.
Click to flip
What is the role of charge polarity on the direction of force in a magnetic field?
Click to flip
Positive charges follow the right-hand rule, while negative charges follow the left-hand rule.
Click to flip
What happens to a moving charge parallel to the magnetic field?
Click to flip
It experiences no magnetic force and continues in a straight line.
Click to flip
What is the effect of velocity direction on the force magnitude on a moving charge?
Click to flip
Maximum force occurs when velocity is perpendicular to the magnetic field.
Click to flip
How does the speed of the moving charge affect the force?
Click to flip
The magnitude of the force is directly proportional to the speed.
Click to flip
Can a magnetic field do work on a moving charge?
Click to flip
No, a magnetic force does no work on a moving charge.
Click to flip
What occurs to a positively charged particle when entering a magnetic field at an angle?
Click to flip
It follows a helical path.
Click to flip
What is the significance of the right-hand rule in magnetic force?
Click to flip
It helps determine magnetic force direction on a positive moving charge.
Click to flip
What is the effect on the path when a charge moves at a high velocity in a strong magnetic field?
Click to flip
The charge will move in a smaller circle due to increased centripetal force.
Click to flip
What happens to the kinetic energy of a charge moving in a magnetic field?
Click to flip
It remains constant because the magnetic force does no work.
Click to flip
What components of force are present in the Lorentz force?
Click to flip
It has both electric (qE) and magnetic (qvB) components.
