Electrons speed and magnetic fields

  1. Dec 23, 2007 #1
    Hi! I am new user to this forums and on the start I have one question:
    "If I increase the speed of the electrons, will the magnetic field strength of the electrons increase?

    Thank you.

    Your answer will be found in the Biot-Savart Law. The electrical current-part, denoted by I, is directly related to the velocity of the charge carriers. Just remember the definition of current and you will conclude that your answer must be YES !

    For a more formal approach, try calculating the induced E-and B-fields of a single electron that makes a circular motion. You will see that B = (1/c2) v x E !
