Are there components of the velocity that cannot be determined by measuring the force if one looks at the formula F = q*B*v?
For non-relativistic cases, the vector form of that equation provides all info concerning the force exerted on a moving charge by a magnetic field:Soaring Crane said:Are there components of the velocity that cannot be determined by measuring the force if one looks at the formula F = q*B*v?
The equation for calculating the velocity of a moving charge in a magnetic field is v = (qB)/m, where v is the velocity, q is the charge of the particle, B is the magnetic field strength, and m is the mass of the particle.
The direction of the magnetic field affects the velocity of a moving charge by exerting a force on the charge that is perpendicular to both the direction of the magnetic field and the velocity of the charge. This force causes the charge to move in a circular path, with the velocity perpendicular to both the magnetic field and the force.
The force exerted on a moving charge by a magnetic field is directly proportional to the strength of the magnetic field. As the magnetic field strength increases, the force on the charge also increases.
No, the velocity of a charged particle in a magnetic field can never be zero. This is because the magnetic force on the particle is always perpendicular to its velocity, causing it to continuously move in a circular path.
The direction of the magnetic force on a moving charge can be determined using the "right hand rule". With the thumb pointing in the direction of the velocity, and the fingers pointing in the direction of the magnetic field, the direction of the force can be determined by the direction the palm is facing.
