Question

A charged particle moving in a magnetic field will be deflected in a direction ____________________ to the magnetic field.

Answer 1

please post this in the physics section next time
this time I will tell you that the force acting on a charged particle moving through a magnetic field is given byis given by\[\vec F=q\vec v\times\vec B\]since the force is the result of a cross-product, you know the force will be perpendicular to the magnetic field.
