Introduction:
The experiment consists of two coils, Constant Current Power Supply and Gauss meter. The Gauss meter 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.
- Weight : 20 Kg. Approximately
The following studies Biot Savart’s Law 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, >a and <a, where a is the radius of the coil.
Legend
Line 1 : Magnetic Prole when the distance between the coils is > a
Line 2 : Magnetic Prole when the distance between coils is = a
Line 3 : Magnetic Prole when the distance between coils is < a Superimposition overlaps completely
Apparatus consists of the following
1. Digital Gaussmeter
- Range : 0-200,
- Resolution : 0.1G,
- Accuracy : ± 0.5%,
- Display : 3½ digit 7 segment LED with auto polarity.
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.
Note: There may be any change in specification due to continuous R & D without notice.
