    Does a charge moving with constant velocity has an electric and magnetic field?

    Any charge has an electric field surrounding it, radially.

    Any charge in motion creates a magnetic field in a direction perpendicular to the direction of motion of the charge.

    usama92pak does not find this helpful : As a=F/m when charge moves with consantant velocity then F=0 (as a=0) then E=o.
    That's why I said PERPENDICULAR because F = ma applies only when the acceleration is in the same direction as the force. Learn your laws well.

    What about a current carrying conductor? Charges flow through the conductor at constant speed. Don't they create a magnetic field? Do you know Flemming's Left Hand Rule?
