Magnetic Field Around a Wire, I - MagLab If the conductor is a wire, however, the magnetic field always takes the form of concentric circles arranged at right angles to the wire. The magnetic field is strongest in the area closest to the wire, and its direction depends upon the direction of the current that produces the field, as illustrated in this interactive animation. Reverse Magnetic Field of a Straight Wire - Concepts of Physics Join all the points by a smooth curve to give a field line. Similarly, draw other field lines at different distances from the wire. Draw arrows on the lines to show the direction of the magnetic field. If the current is strong, say about 2 A, the lines will be nearly circular. If the current is weak, it will produce a weak magnetic field.

Determining the Direction of the Magnetic Field Around a Straight ... Magnetic Field (B): A field possessing magnetic force, or magnetism.
