Question

How can you increase the sensitivity of spherometer ?

Answer 1

Answer:

By using an electromagnet with a variable resister to finely-balance your spherometer's intrinsic, counter-clockwise torque--assuming that you are in the Northern Hemisphere.

If you are in the Southern Hemisphere, then you'll simply need to reverse the polarity of your electromagnet.

Explanation:

Answer 2

you can increase the Sensitivity by using an Electromagnet.

Explanation:

A spherometer is an instrument for the precise measurement of the Radius of curvature of a sphere or a curved surface. originally, these instruments were used by opticians to measure the curvature of the surface of a lens.

You can increase the sensitivity by using an electromagnet with a variable resistor to finely balance your spherometer's intrinsic, counter - clockwise torque , assuming that you are in the northern Hemisphere.

If you are in Southern hemisphere, then you"ll simply need to reverse the polarity of your Electromagnet.
