1. The problem statement, all variables and given/known data A pair of wires carry a current I=2.4 A to and from a solenoid. The solenoid contains 600 coils of wire wrapped in a cylinder 15 cm long and 1 cm in diameter. a.) What is the magnitude and direction of the magnetic field at point A d1= 5 mm from the near wire and d2= 7 mm from the far wire? 2. Relevant equations B=(m0*N*I)/l 3. The attempt at a solution We know m0, N, and I but I'm not sure if the length is supposed to be the 5 mm or 15 cm? Obviously which ever I use I'll have to convert to meters. Do I just plug that stuff into the equation above and I'll have the answer? After I find the magnetic field magnitude with the equation, I'll use the right hand rule to find out which direction it points.
