(Don't try this at home, as it will permanently magnetize and ruin the TV.) To illustrate this, calculate the radius of curvature of the path of an electron having a velocity of 6.00×107m/s (corresponding to the accelerating voltage of about 10.0 kV used in som…
Magnetic force can supply centripetal force and cause a charged particle to move in a circular path of radius r=mvqB, where v is the component of the velocity perpendicular to B...Magnetic force can supply centripetal force and cause a charged particle to move in a circular path of radius r=mvqB, where v is the component of the velocity perpendicular to B for a charged particle with mass m and charge q.
