The magnetic field direction follows the &quot;right handrule&quot;. In other words, if you hold the wire with your right hand so that your thumb points in the direction of the current as you close your four fingers around it. Then the direction of the magnetic field is the same as your closing fingers. That is, it is circular around the wire.Regards, Frank
