A multiple choice question is a type of question where the respondent is presented with a list of possible answers, and they must select the correct one.
Magnetic force is a force that is exerted on a charged particle or a magnet when it is placed in a magnetic field.
The magnetic force on a particle depends on the strength of the magnetic field, the charge of the particle, and the velocity of the particle. It can either attract or repel the particle, depending on the direction of the magnetic field.
The strength of the magnetic force on a particle is affected by the strength of the magnetic field, the charge of the particle, and the velocity of the particle.
The magnetic force on a particle can be calculated using the formula F = qvB, where F is the force, q is the charge of the particle, v is the velocity of the particle, and B is the strength of the magnetic field.
