9. At the latitude of the Chicago area the earth's magnetic field points north and down at an angle of 420 with respect to the horizon. Traffic sensors buried in the roadway use this field to sense the presence of vehicular traffic. A particular sensor is made up of ten turns of copper wire shaped into a square 1.5 m on a side. The entire 10 loop circuit has a resistance of 0.64 ohms. When a specific make and model car first moves over a sensor at a speed of 5.0 km/hr, it reduces the vertical component of B field in the loop at a rate of 0.020 Tesla/s. a) (5 points) What EMF is induced in the loop? b) (5 points) What is the magnitude and direction of the current induced in the loop? Indicate the direction of the current as clockwise or counterclockwise as seen from above
