1. The problem statement, all variables and given/known data A wire carries a current of 30A along the x-axis from x = 0 to x = 3.0 cm. Determine the magnitude in uT of the magnetic field at the point y = 4.0 cm on the y-axis. 2. Relevant equations dB = (u/4pi) ((Ids x r)/r^2) 3. The attempt at a solution We tried using this formula, but it didn't work. We are lost. Please help! Be descriptive if you can.
