Suppose that the polarity is reversed in the figure above so that the south end of the magnet is closer to the loop in each case. the south end is pushed into the loop from left to right. the change in flux is: flux caused by magnetic field lines pointing to the to oppose this change, the induced current must keep the flux from thus, the induced current produces a magnetic field that points to the . thus, as viewed from the left, the induced current is the south end is pulled away from the loop from right to left. the change in flux is flux caused by magnetic field lines pointing to the . to oppose this change, the induced current must keep the flux from . thus, the induced current produces a magnetic field that points to the . thus, as viewed from the left, the induced current is .

We all use gps today, even if we don't drive yet. i bet you have been in the car with a parent and they have asked you to get out your phone to find a specific location. in your car, on the phone, you are using a very sophisticated technology. gps satellites circle the earth twice a day in a very precise orbit and transmit signal information to earth. gps receivers take this information and use trilateration to calculate the user's exact location. essentially, the gps receiver compares the time a signal was transmitted by a satellite with the time it was received. the time difference tells the gps receiver how far away the satellite is. now, with distance measurements from a few more satellites, the receiver can determine the user's position and display it on the unit's electronic map. what type of signal is utilized by the gps satellite?
