Magnetic lines of flux on a conductor

When a current flows through a conductor, it generates a magnetic field. The direction of the field is determined by the direction of the current flow. The diagrams below introduce the concept of current flow within a conductor (a dot for towards and a cross for away) and demonstrates the application of the right hand grip rule.

Questions on magnetic lines of flux on a conductor appear in the 2330-202, 2330-203, 2330-301 and the 2357-309 exams.
