Forces caused by magnetic fields

What is it? A device used to measure very small currents (like those produced by a magnetic field)

F = Bqv F = B = q = v =

F = Bqv F = force (N) B = magnetic field strength (Teslas) q = the charge on a particle © v = velocity (m/s)

If the particle you are dealing with is an electron, its’ charge will always be 1.6 x C We used this in chapter 20…

1. A beam of electrons moving at a speed of 3 x 10 9 m/s passes thru a magnetic field that has a strength of.0005T. What force acts on the electrons in the magnetic field? 2. Electrons in a cathode ray tube are moving at 6 x 10 4 m/s and pass thru a magnetic field with a force of 0.45 N. What is the strength of the magnetic field?
