Magnification power of ocular lens times the magnification power of objective lens

total magnification

decreases as lens gets smaller and increases as it gets larger

What happens to magnification as objective lens length increases or decreases?

decreases as magnification increases

What happens to working distance as magnification increases or decreases

never

When should you use course focus knob when viewing under high power?
