Magnetic Field

  1. Dec 4, 2005 #1
    Hi everyone

    I would like to ask, how can i resolve this task:

    electron is moving inside the magnetic field with density 0.002 T on the shape of screw with radious 2 cm (centimeters) and height of screw 5 cm. What is electron's speed? The result is 7.6 Mm/s but im trying to see how do i get this result?

    Thank you for formulas and tips.
