We offer Magnetic Field Measurement Apparatus, 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 > aLine 2- Magnetic Profile when the distance between coils is = aLine 3- Magnetic Profile when the distance between coils is < a- Superimposition overlaps completelyApparatus consists of the following:1. Digital GaussmeterRange: 0-200Resolution: 0.1GAccuracy:+-0.5%Display: 3.5 digit 7 segment LED with autopolarity.2. Two CoilDiameter: 200mmNumber of turn: 10003. Constant Current Power SupplyCurrent: 0-0.5A Smoothly adjustableLine Regulation: +-0.2%for 10% mains variation.Load Regulation: +-0.2% for 0 to full load.Display: 3.5 digit 7 Segment LED Display.Protection: Against overload/ short circuit.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.The experiment is complete in all respect.
