I know that F = I x B but when I try to apply it I don't get anywhere. (I) is a vector tangent to a point on the solonoid. (B) is a vector parallel to the central axes of the solonoid. So I x B or (F) would be a vector perpendicular to the central axes of the solonoid ?
I have been doing some experimenting with a relatively short cylindrical permanent magnet and a solenoid with DC current applied. I would like an explanation as to why these two things happen. The OD of the cylindrical magnet is just a little bit smaller then the ID of the solenoid.
