WebFeb 20, 2024 · The magnitude of the magnetic force F on a charge q moving at a speed v in a magnetic field of strength B is given by. (22.4.1) F = q v B sin θ, where θ is the angle between the directions of v and B. This force is often called the Lorentz force. In fact, this is how we define the magnetic field strength B --in in terms of the force on a ...

WebThe method to find the magnitude and direction of the resultant vector is as follows: Suppose u have 2 vectors: A & B. A X B = A B sin (t) where t is the angle b\w the 2 vectors. This is the magnitude. to find direction, jst put the palm of ur right hand in the direction of vector A. Now curl ur fingers in the direction of vector B. WebThis particle experiences a force with magnitude F = qvB perpendicular to its velocity. A force perpendicular to the velocity results in centripetal acceleration a = F/m = v 2 /r. The particle will move along a circular path. The radius of the circle is r = mv 2 /F = mv 2 /(qvB) = mv/(qB), and the circle lies in a plane perpendicular to B. The ... table rotating plate
