... For translational motion, Newton's second law connects the force acting on a particle with the resulting acceleration. There is a similar relationship between the torque of a force applied on a rigid object and the resulting angular acceleration. This equation is known as Newton's second law for rot ...

... When a particle has a velocity at an angle to the magnetic field, there is a parallel component and a perpendicular component, meaning it has constant speed and follows a circular path. Combining these shows us it follows a helical path. The magnetic force on a current-carrying wire is given as: . T ...
