What physical aspect of a converging lens affects magnification

[NzToker420]

Probably a complete newb question and I know magnification is dependent on how severely the light is bent but what physical aspects cause the light to bend more/less?
I was told it's the thickness so do thin or thick lenses bend light more severely? and which would result in greater magnification?
Do Plano convex, miniscus convex etc make a difference?
Since the lens is thicker at the surface than the edge does any difference in this affect magnification?
Lastly does the curvature of the lens affect magnification?
Hopefully this is all making sense and any help would be greatly appreciated.
All this is for research on my chosen device being an optical microscope.
Cheers

The physical aspects that cause light to bend more or less are the shape and composition of the lens. The thicker the lens, the more it will bend the light (this is why thicker lenses have a higher magnification). Plano-convex and miniscus convex lenses have different shapes and compositions that affect the bending of light differently, so the amount of magnification they provide can vary. The curvature of a lens also affects the magnification, as lenses with a steeper curvature will bend the light more severely. Finally, the difference in thickness at the surface and edge of a lens can also affect the magnitude of the bending of the light, and thus, the amount of magnification.
