How megnetic field produce a current
WebExample 1: Calculating Current that Produces a Magnetic Field. Find the current in a long straight wire that would produce a magnetic field twice the strength of the Earth’s at a … WebFrom the right-hand rule, the magnetic field d B → at P, produced by the current element I d l →, is directed at an angle θ above the y -axis as shown. Since d l → is parallel along the x -axis and r ^ is in the yz -plane, the two vectors are perpendicular, so we have d B = μ 0 4 π I d l sin π /2 r 2 = μ 0 4 π I d l y 2 + R 2 12.13
