January 7, 2014 Reply darcy funk So what does 45 degrees tell us. How is that measuring the earths magnetism? June 8, 2014 Reply Raghavendra Maiya good experiment but does not prove the earths magnetic field's strength. because it depends on the distance of the other magnet too. if you have more powerful magnet then u need to keep it little far from the current magnet.
