| The purpose of this test data was to identify how far out the magnetic | ||||||||||||||
| field extended and what is polarity was at varying distances from the edge of the | ||||||||||||||
| magnet. | ||||||||||||||
| The magnet in this example is 3 of my 4 x 6 x 0.5 inch N42 plates combined into | ||||||||||||||
| a 1.5 inch thick plate monster. | ||||||||||||||
| The numbers in green are South Pole and the readings in red are North Pole | ||||||||||||||
