In the figure above, there are two wires carrying different currents in the same direction.

What is the direction of the magnetic field at point ?

Consider the given wire:

In which direction should the electrons flow through the wire if the electric field generated inside the loop points out of the screen?

What is the direction of the magnetic field at a point ?

The magnetic field of the earth points from geographic south to geographic north, indicating the the geographic south pole is actually a magnetic south pole. If this magnetic south pole were generated by current around the equator moving in a wire, which way would the conventional current be traveling?

In the given diagram, what is the direction of the magnetic field at a point ?

In the given diagram, what is the direction of the magnetic field at a point ?

You have two current-carrying wires layed parallel to each other like below.

Point R is halfway between each of the wires. If the wires carry the same current I, what is the direction of the magnetic field at point R?
