Measuring Apparatus Of Hysteresis Loop And Magnetization Curve Of magnetic Material

DESKRIPSI / SPESIFIKASI TEKNIS

The hysteresis loop and magnetization curve of magnetic material indicate the basic characteristics of magnetic material. Fero magnetic materials are extensively used in varies fields such as industry, transportation, communication and electric appliance. Therefore, the measurement of basic characteristic of the magnetic materials is very important in practice and college physics experiment. The experiment is collected into the physics experimental teaching syllabus in colleges.

Features

►► With high accuracy digital teslameter, the apparatus can accurately measure magnetic induction B of micro gap existed in magnetic material.

►► It can demagnetize or magnetize the sample during the measurement of DC magnetic characteristic of the material, which provides students an occasion of learning the basic concept of magnetism and operating.

►► It can make a micro parallel gap in the rectangular sample, which is convenient for student measuring the magnetic induction distribution in the gap and calculating the magnetic field strength H (including the correction due to gap), so as to better understand Ampere loop law.

►► The apparatus is capable of testing three different magnetic materials, which enables students to understand magnetic characteristic of a variety of typical materials.

The measuring apparatus is more practical and significant compared with the traditional ballistic galvanometer and dynamic method of capacitance integrator. It can be sued for physics experiment in universities and colleges and design experiments.

Experiments

►► Finding out the relationship of density B of remanence in sample and location X with a digital teslameter, measuring uniformly distributed range of field density along X direction;

►► Learning demagnetization fro magnetic sample, measuring initial magnetization curve and hysteresis loop of sample;

►► Learning application of Ampere law in magnetic measurement.
