 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

Apparatus consists of the
following:
1. Digital
Gaussmeter Range: 0-200 Resolution:
0.1G Accuracy: 0.5% Display: 3½ digit 7 segment LED with
autopolarity.
2. Two Coil Diameter:
200mm Number of turn: 1000
3. Constant Current Power
Supply Current: 0-0.5A Smoothly adjustable Line
Regulator: 0.2%for 10% mains variation. Load Regulator: 0.2
% for 0 to full load. Display: 3½ digit 7 Segment LED
Display. Protection: Against overload/ short current.
The 2 coils are mounted on platform one coil
is fixed and other coil move smoothly on a rail along with the
axis of the coils.
