1. The problem statement, all variables and given/known data A small current element at the origin has a length of 2.0mm and carries a current of 2.0A in the +z direction. Find the magnitude and direction of the magnetic field due to this current element at the point (0,3.0m,4.0m). 2. Relevant equations Biot-Savart Law: dB=(mu/4pi)(Idl cross r(hat))/(r^2) 3. The attempt at a solution I attemped the problem by integrating the biot-savart law holding everything constant except for dl. However, this does not give me the correct answer, which by the way is -9.6pT in the +i direction.
