Experimental measurement of magnetic field generated by neodymium magnet

Abstract

Permanent magnets are one of the basic components of magnetic passive suspension system using superconductors. Generating magnetic field neodymium magnets are placed along the system’s guide. Presented experimental studies were conducted to measure the intensity of the magnetic field, generated by a single neodymium magnet. The Brockhaus Measurements magnetic field gauge BGM 101 was used to build the measuring station. The mechanical part was based on the D4128R110 stepper motor and the ATmega2560 microcontroller, which controlled the Motor Shield module containing L293D. Configuration of proposed measuring station allows to move the gaussmeter probe horizontally, above the magnet. The controllable speed of measurement table enables to obtain accurate and reproducible magnetic field measurements.
