What is the relationship between the magnetic field density and the distance from the surface of a magnet halfway between the poles?

The diagram shows four locations in the electric field of a positive point charge m. at which location is the electric potential the greatest.

Which of the following changes will increase the capacitance of a parallel-plate capacitor? (there could be more than one correct choice.) a) increase the charge on the plates b) decrease the poten5al between the plates c) increase the potential between the plates d) introduce a dielectric material between the plates e) decrease the separation between the plates

Sort the images based on whether there's a force of attraction or repulsion between the magnets shown. attraction repulsion
