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:
Study of magnetic field due to one coil and calculation of its diameter.
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.
Magnetic Profile when the distance between the coils is greater than a
Magnetic Profile when the distance between coils is equal to a
Magnetic Profile when the distance between coils is less than a - Superimposition overlaps completely
Apparatus consists of the following:
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: 31/2 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.
