Im sure Google can answer this question but thought others might want to know also.
So can you use a smaller/weaker magnet on inside of glass and a larger/stronger on the outside of glass; resulting in a stronger magnetism than just using the smaller ones? Or...will the magnetism strength only be as strong as the smaller of the two?
