What are the magnet knowledge?

2017-06-15
? ? ? ?I really want to elaborate the vertical bar magnet from the middle incision can be from the new contract, as for mutual exclusion, I think some of the following reasons, may use a bar magnet pole direction is not completely parallel to the surface of the upper and lower part of the section, slightly angle. Then the formation of the magnet may be different, such as the situation can be completely vertical.
? ? ? This will be mutually exclusive, of course, the true deviation angle should not be so great.
? ? ? By the way, are you sure you have done experiments with a lab bar magnet? Because our more common magnet is a ring magnet, the ring magnet is distributed on the upper and lower surfaces. It will repel after disconnecting.
? ? ? As for the verification of reasons I have explained the correctness of the method is that the two part test bar magnet disconnect, when they are close to exclude each other, when they are slightly punctured when it is attracted to each other, it can be proved that the conclusion is correct, if they are to rub rejection.
