I was bored , so I thought I 'd take apart a guitar humbucker I had lying around , and test its magnetic polarity . To do this , I took a fridge magnet , and test which end would repel it . Turned out , there was no end of the pickup magnet that repelled the fridge one . I tried everywhere on all six sides , and I did n't even notice any difference in the degree of attraction .

Question: What may happen after they noticed the magnet would not repel ?
Answer: They did experiments to try and figure out why .They called and asked a friend for advice .They out the magnets down and did something else .None of the above choices .
