Use the formula a = |q|*v*B / m, where q is the charge, v is the velocity, B is the magnetic field, and m is the mass. This is alos equal to a = F / m.Since the velocity is not given, use the formula v = (2*KE / m)^(1/2).eport Abuse.

When the field lines are close together, the magnetic field is strong. When the field lines are far away from one another, the magnetic field is weak. A unit of measure of the strength of the magnetic field is the Gauss or the Tesla. So, let's look at some field lines and magnetic fields around various magnets. For these diagrams, I used a small arrow inside the magnet to show the direction of the magnetic field lines. The head of the arrow would be pointing to the North pole of the magnet and away from the South pole of the magnet. Bar Magnet.
