the figure below represents the xy plane that cuts perpendicularly two infinite and parallel wires that carry a current I, of the same magnitude, but in opposite directions. Draw the vectors to show the magnetic field B of each wire and resultant field Br at point P. NOTE: THE SECOND IMAGE IS THE ANSWER. I WOULD LIKE TO KNOW WHY Br = 2Bsin(θ) So, explain in details why Br = 2Bsinθ, there is no need to calculate anything else
