At point P, a distance d = 3.18 cm from a current carrying wire, the magnetic field generated by the wire is found to be B = 8.82 X 106 T directed out of the screen. 1:? Figure 1. Point P is a distance d away from a current carrying wire. Part 1) What current is flowing through the wire? Give a positive answer if it ows up the screen and a negative answer if it ows down the screen. I: A Part 2) Which of the following best describes the magnetic field around the wire? C] The magnetic field drops off as 1Idistance from the wire. C] The magnetic field lines are straight lines. C] The magnetic field drops off as an inverse square of the distance from the wire. C] The magnetic field lines form circles. Part 3) A wire with the same current as the first wire is placed parallel to the first wire but with the current flowing in the opposite direction. What is the force per unit length on the first wire due to the current in the second wire? I -I Wire 1 Wire 2 Figure 2. Two wires with opposite flowing currents are separated with a distance of d. Note: Give a positive answer if it is to the right and a negative answer if it is to the left. sm
