A charge moves through a magnetic field with a certain velocity. The direction of force can be obtained by applying
The direction of force can be obtained by applying Fleming's left-hand rule.
Fleming's Left-Hand rule:
Fleming’s Left Hand Rule states that if we arrange our thumb, forefinger, and middle finger of the left-hand perpendicular to each other, then the thumb points towards the direction of the magnetic force, the forefinger points towards the direction of the magnetic field, and the middle finger points towards the direction of the current(or the direction of the movement of the positive charge).
Therefore, the direction of force can be obtained by applying Fleming's left-hand rule.
