05 (20 points): The two long wires shown in the figure carry currents of 10.0 A and 5.0 A in the opposite direction and are separated by 10 cm. a) Calculate the magnetic field (with direction) at the midway between the two wires (at point A)? 11=10A 12=5A A . P 10 cm 10 cm b) Calculate the magnetic field (with direction) at point P which is 10 cm to the left of I1? c) Calculate the force per unit length on wire In due to wire 12 (magnitude and direction) d) Assume that a coil of 10 loops and a radius of 4 cm is placed between the two wires such that point A locates at the center of the coil. What is the magnitude and the direction (CW or CCW) of the current in the coil that makes the net magnetic field at point A equals zero. |1=10A 12=5A
