Question

Help.

Answer 1

Sketch the field lines for the magnetic fields associated with the currents shown in the diagram below. (The dots and crosses show the direction of the currents.)
WARNING: The drawing is a a bit crappy. sorry. :/

Answer 2

Hi! Do you know that the magnetic field "spins around" a wire? Well, the direction of the field at a point ((due to one wire)) is always perpendicular to the imaginary line that connects it to the wire. But perpendicular could be two ways.
