= Hall Effect Apparatus BTC-6

(a) Electromagnet 0-7.5KGauss

(b) Power Supply

(c) Digital Gauss Meter with Probe Extra at cost

(d) Hall Set Up

(e) Hall Probe GE Xtal(P type or n Type)

ELECTROMAGNETS -

Field Intensity 10KG. +- 5% in an air gap of 10mm., Air- Gap is continuously variable upto 100mm. with two way.

Pole Pieces 50mm. diameter, Normally flat faced pole pieces are supplied with the magnet. Energising Coils Two , Each coil is wound on NON-magnetic formers and has a resistance of 10ohms. approx. Yoke Material U shaped soft IRON.

POWER SUPPLY for Electromagnets-

A high current Continues power supply is workable on 220v50Hz with output is 90 volts 6Amp(approx.) depend on the load (electromagnets).The power supply consist One Current Meter, A.C./ON switch to ON the power, Level knob tocontrol current in Electromagnets. The magnetic strength can be variable by this knob, Output terminals are to take output from power supply to connect it to Electromagnets.

CONSTANT CURRENT POWER SUPPLY-

It is a Constant Current power supply 0-20 milliamp , 0-200mV. The Variation in the current are achieved by a potentiometer. The supply is a highly regulated and practically ripple free d.c. source . The current measured by the digital Panel meter, a 3.5 digit single chip A/D coverter IC 7107 have been used . It has high accuracy like auto Zero to less then 10uV, zero drift less then 1V, and roll over error of less than one count. Sine the use of internal

reference has been used. This voltmeter is much more convenient to use in Hall Experiment ,because the input of either polarity can be measured

Introduction

Nuclear Magnetic Resonance (NMR) was discovered by Bloch and Purcell in the year 1945. Over the years it has developed into a very useful and powerful tool in solid state physics, chemistry and biology. In medical application this technique, under the name Magnetic Resonance Imaging (MRI) has been developed as an excellent imaging method for clinical diagnosis. In this method use is made of Zeeman interaction of the magnetic dipoles associated with the nucleus when placed in a external magnetic field.

    Exp-1 To determine the wavelengths of Balmer series in the visible region from hydrogen emission.
    Exp-2 To determine the Rydberg constant.
    Principle and Working:
    Hydrogen atoms in a discharge lamp emit a series of lines in the visible part of the spectrum. This series is called the Balmer series which continues into the ultraviolet range. Rydberg generalized the Balmer’s formula in terms of wave numbers to describe wavelengths of spectral lines of many chemical elements. For hydrogen the Balmer’s formula becomes a special case of Rydberg’s formula and is given by

    1/λ=R(1/22 - 1/n2)

    where n are integers, 3, 4, 5, … up to infinity and
    R is Rydberg constant ( R = 4/B where B is the Balmer’s constant). In the present setup, the spectral lines of hydrogen is observed by means of diffraction grating. The wavelength of the visible lines of Balmer series of hydrogen are measured by spectrometry.
