Quinck’s Tube Experiment

Objectives To measure the magnetic susceptibility of a given paramagnetic sample (FeCl3). Principle The Quinck’s method is used to determine magnetic susceptibility of diamagnetic or paramagnetic substances in the form of a liquid or an aqueous solution. When an object is placed in a magnetic field, a magnetic moment is induced in it. Magnetic susceptibility x is the ratio of the magnetization I (magnetic moment per unit volume) to the applied magnetizing field intensity H. The magnetic moment can be measured either by force methods, which involve the measurement of the force exerted on the sample by an inhomogeneous magnetic field or induction methods where the voltage induced in an electrical circuit is measured by varying magnetic moment. Key Features Compact Setup – The apparatus design is compact and yet effective to perform the experiments with ease. The simple connections and stand to hold the teslameter probe, makes it easy to handle. Custom Quinck’s Tube – Specially designed quinck’s tube can be attached seamlessly on the setup and dimensions are controlled such that it fits perfectly between the pole pieces.
