A wire is place on the x-axis, and a second wire is placed on the y-axis. The current in the horizontal wire is 3.0 A. The current in the vertical wire is 4.0 A. (Note the different currents.) a) What is the magnitude and direction of the net magnetic field at the point (1.0 m , 1.0 m)?b) What is the magnitude and direction of the net magnetic field at the point (-1.0 m , -1.0 m)? Suppose a tiny loop is placed at each of these points. If the horizontal current starts decreasing, and the vertical current starts increasing, both at the rate of 2.0A per sec, in which direction will a current flow in these loops?
