The direction of the magnetic force on a charged particle is perpendicular to both the direction of the particle's velocity and the direction of the magnetic field. The magnitude of the force depends on the charge of the particle, the strength of the magnetic field, and the speed of the particle.
The magnetic field is what creates the force on a charged particle. Without a magnetic field, there would be no force on a charged particle and it would continue to move in a straight line.
The direction of the magnetic field determines the direction of the magnetic force on a charged particle. If the magnetic field is parallel to the particle's velocity, there will be no force. If the magnetic field is perpendicular to the particle's velocity, the force will be at a right angle to both the field and the velocity.
A positively charged particle will experience a force in one direction when moving in a magnetic field, while a negatively charged particle will experience a force in the opposite direction. This is due to the fact that positive and negative charges move in opposite directions in a magnetic field.
Yes, magnetic forces can be used to accelerate charged particles. This is the principle behind devices such as particle accelerators, which use magnetic fields to accelerate charged particles to high speeds for various experiments and applications.
