What is the reason for magnetism why the lines of force around a bar magnet are curved and is there any magnetic field?

It has to do with the geometry. Magnetic fields are at right angle to electric fields. The main diff is magnetic fields HAVE to be closed loops, in order to fit properly across the geometry of the electric field lines.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
