Can you solve the MAGNET RIDDLE? ft YouTube CEO Susan Wojcicki

there is another way to figure the magnetic field you are in a office use a paper clip "steel"  bend one side straight and draw it across the fist bar in a north to south direction and do this about 20 to 30 time though more is better  after you do this use the string to hold it in the center and let it spin freely so that it will act as a compass to point in a north to south line this is also ho to make a compass in a survival situation the reason this works is you a aliening magnet field from a load stone or permeant magnet to the steal paper clip
