Questions:

  1. What happens to the magnetic field strength as distance increases?




  2. What would the magnetic field strength be at 7 cm?




  3. What would the magnetic field strength be at 16 cm?




  4. How does this help explain why the magnetic field of the earth does not overpower the magnetic field of the bar magnet when we hold a compass to it?
