hmmmm, i think i need to customize it for exploring and visualization of

The velocity of a charged particle moving in a magnetic field is always perpendicular to the direction of the field.
37% think it is true, but the answer is false. it could be a supposition of uniform velocity and circular motion, thus there is an angle =! 90[sup]o[/sup] between v and B, much like a helix path

a. Recitation of formula: v, B and F are always perpendicular according to left hand or right screw law 81
b. No reason 19
