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.

1. Using a larger volume of thermometric liquid.
2. Using a narrower capillary bore.
3. Using a thermometric liquid which expands more for the same change in temperature.
yes, even more when concentrating on the area
Touch ... the number of receptor cells.
They would be more sensitive to heat and less to cold. The fat in your body acts as a 'coat' or jacket would. Imagine wearing heavy coat in the summer.
More sensitive areas have more receptors that sense pressure, temperature, etc., thus making them more sensitive to touch than others. For example, fingertips have more receptors than the back of the leg and are therefore more sensitive. I think there are more there because they are considered more important to the body or easily damaged. The face, with its proximity to the brain, has more receptors than between your toes. Although, I think the middle of the back doesn't have as many even though it is near the spine, so there may be more to this.
why we use sensitive balance
The reason a spherometer is called a spherometer is because it measures the radius of a sphere.

abt spherometer
spherometer is an instrument used to measure the curvature of a sphere
A spherometer is an instrument for the precise measurement of the radius of a sphere. The spherometer directly measures a sagittal. Since the spherometer is essentially a type of micrometer, it measures very small things like millimeters.
The difference between screw gauge and spherometer is that spherometer can measure the dimensions of spherical surfaces but screw gauge cannot
because to determine the radius of curvatureof a given spherica surface by spherometer
drysdale
The distance moved my the screw in one complete rotation in the circular scale is called the pith of spherometer.
In general in any screw type instrument such as spherometer or screw gauge or micrometer the least count = pitch / no of head scale divisions Spherometer has an advantage of finding the depth in case of curved surfaces.

3/16" thick is the minimum thickness Sagiita that can be measured by means of spherometer.
