Question

I. I. If two infinitely long current carrying conductors are close together each experiences a force. If If and h are the currents flow through the each conductor in same direction and separation of them is a, derive an expression to find the force acted on length L in each ofthe wire. II. A current of 3 A flows down each of two long, vertical wires, which are mounted side by side 5 cm apart. Show on a diagram the magnetic field pattem in a horizontal plane, indicating clearly the direction ofthe magnetic field at any point. What is the magnitude and direction of the force on a 25 cm length of a wire?
