A wire of 1.0 m length carries the current I1 = 25 A. Another wire of the same length, parallel to the first one carries the current I2 = 15 A. As a result, the wires attract each other with the force F = 1.5 mN. What is the distance between the wires? Are the currents of the same or opposite directions? What of the following statements is/are correct? A. The current in one wire create electric field, which exerts...
