Introduction
The experiment consists of two coils,
Constant Current Power Supply and Gaussmeter. The Gaussmeter
probe is mounted on a rail with a scale. It can move smoothly
and precisely for measurement of magnetic field along the
centre of the coils.
The following studies can be carried
out with the set-up:
1. Study of magnetic field due to one coil
and calculation of its diameter.
2. Study of principal of super-imposition of
magnetic field due to 2 coils by keeping the distance between
the coils at a, greater than a and less than a, where a is the
radius of the coil.
Legend:
| Line 1 |
Magnetic Profile when the distance
between the coils is greater than a |
| Line 2 |
Magnetic Profile when the distance
between coils is equal to a |
| Line 3 |
Magnetic Profile when the distance
between coils is less than a – Superimposition overlaps
