Current Density and Current

  1. Mar 24, 2007 #1
    Near Earth, the density of protons in the solar wind (a stream of particles from the Sun) is 8.90 cm-3 and their speed is about 490 km/s.

    a. Find the current density of these protons.



    b. If Earth's magnetic field did not deflect the protons, what total current would Earth receive?

    You should:

    1) post homework questions in our homework section

    2) follow the rules there, of which the main rule is: show some work first.

    I move this to hw, but you shouldn't expect any answer before you show some work.
