1. The problem statement, all variables and given/known data A square with each side of 5 cm in length.Now if 4 parallel wires in each 4A current is flowing were placed on the vertex of the square.How can I find the center of the square of the magnetic strength? 2. Relevant equations I am not sure what equation should be used.If I knew I would solve the problem myself. 3. The attempt at a solution Since the wires are placed at the corners i.e vertex of square, then the 4 wires will make another square like structure.
