5) {2 point) The Earth's magnetic field not only changes in direction it also changes in strength. If the present weakening trend continues the magnetic field may reduce to zero strength in 1500 years. It would then gradually gain strength and the north and south poles will be reversed. Considering that the Earth's magnetic field protects us and ourtechnology from harmful solar radiation, how might technology and life on Earth be affected when this happens? 6) {2 points) A proton passes by a current carrying wire as shown in the diagram. Determine the direction of the magnetic a. Field around the wire on the same side as the proton. direction of travel i p+ 1:). Force on the moving proton as it passes the wire. 7) (1 point) When a charged particle moves parallel to the magnetic field the magnetic force acting on the charge is: 8) {4 points} Refer to the diagram. A magnet is A 3 moved at uniform speed between two _ solenoids. The magnetic polarities at )))) )))) positions A and B, respectively. are: A: B. The direction of the induced current in coils 1 and 2. respectively viewed from position A and B are (use the terms clockwise or counterclockwise): A: B
