i would really appreciate if someone could help me out with this one. i m preparing for an exam and this question is a question from papers of previous years and its bugging me because it seems very specific in that i cant seem to find anything like it in text books.(adsbygoogle = window.adsbygoogle || []).push({});

what i m mainly stuck on is if a negative charge is spread over the magnet does this mean the direction of the magnetic field reverses from north to south to south to north?

A bar magnet has been given a negative charge -Q, spread uniformly over the magnet.

the Gaussian cylinder shown at right with end caps A and C and a curved side B. the centre of cap A coincides with the centre of the bar magnet.

(a) is the total electric flux through the top end of the cap, A, positve, negative or zero?

(b) is the total electric flux through the entire gaussian surface, consisting of sides A,B, and C, positive, negative, or zero?

(c) is the total magnetic flux through the top end cap, A, positive, negative or zero?

(d) is the total magnetic flux through the entire gaussian surface, consisting of sides A, B, and C, positve, negative, or zero?
