Relative moving charge

  1. Jun 29, 2008 #1
    So what is the answer to "if I am moving at velocity v with respect to a single charge, charge q, will I see the electric field as I would at rest with respect to the charge, or will I see a magnetic field? what will be the strength of the magnetic field?"

    You will observe a magnetic field which has the value

    B = -[itex]\gamma[/itex][itex]\beta[/itex]xE

    where E is the electric field as measured in the charges rest frame. Note: that [itex]\beta[/itex] is supposed to be in bold because its a vector.
