Wouldn't there be a magnetic force?

mercredi 30 avril 2014

Our professor proposed a scenario during lecture that went like this, There is a wire of infinite length that has a current. At a short distance from the wire is a single charge which is stationary relative to the wire.



What i dont understand is this, since the charge has a velocity relative to the moving electrons which make up the current in the wire, why is there no magnetic force?
