Homework Statement
Ill try to translate as good as possible.
Electrons are sent through potential difference of 2500V. Then they get into transverse magnetic field where they move in circular arc with 22cm radius. What is the magnitude of magnetic field?
So the radius is= 22cm
and the potential difference is 2500V.
Homework Equations
B= u0 I / 2 Pi r
I don't know how to calculate I out of this formula, so i can calculate B (magnitude of m.f.)
Or i have missed the solution to this problem completely? Please help
