Compute all parts of given question:
Question: A straight conducting wire carries a 7.8A current in the +y-direction.
Part A: Find the magnitude of the magnetic field that result in a force per unit length on the wire of 0.11N/m in the z-direction?
Part B: Find the direction of the magnetic field that result in a force per unit length on the wire of 0.11N/m in the z-direction.
Please Help and show steps. I am trying to understand how to work this question. Thanks in advance!
