Question

Please help chose and explain the direction that the magnetic field will go towards.

For a long straight wire carrying a current I, the magnitude of the magnetic field, B produced at a perpendicular distance, r from a wire is given by where is the magnetic permeability of free space and is a constant. The amount of electric current, I is measured in Amperes (A) and r is measured in m. Thus the circle formed by the distance r from the wire has magnetic field of the same magnitude. However, the direction of the magnetic field at a point on the circle is the tangent at that point. Since there are two possible directions for the tangent, the direction, by convention, is determined by the right hand rule. Learn more using java applet simulations. Study the applet carefully and answer the following questions.
