The Right-Handed Rule

As current travels through a wire it generates a magnetic field.

| This is the traditional way of demonstrating the right-handed rule. The thumb points in the direction of the current. The fingers show the direction of the magnetic field as it goes around the wire
| Our diagram demonstrate the same concepts. Here the red spheres demonstrate the flow of electricity through the wire while the blue arrows demonstrate the direction of the magnetic field
