A charged particle passing through a magnetic field experiences a force called the magnetic force. This force is perpendicular to both the velocity of the charged particle and the magnetic field direction.
The magnitude of the magnetic force can be calculated using the equation F = qvBsinθ, where F is the magnetic force, q is the charge of the particle, v is its velocity, B is the magnetic field strength, and θ is the angle between the velocity vector and the magnetic field vector.
To determine the direction of the force, you can use the right-hand rule: If you extend your right hand with your thumb pointing in the direction of the velocity vector, and your fingers pointing in the direction of the magnetic field vector, then the magnetic force on a positive charge will be perpendicular to both your thumb and fingers. For a negative charge, the force will be in the opposite direction.
Overall, this can be summarized as: A charged particle passing through a magnetic field experiences a perpendicular magnetic force, which causes it to deflect from its original path, leading to circular or helical motion depending on the initial conditions.
