Model for determining the magnetic permeability of a neodymium magnet

Abstract

A laboratory educational experiment is presented to determine the characteristics of an oscillating circle under the influence of a neodymium magnet Nd₂Fe₁₄B .The oscillating circuit is composed of a coil with an inductance of 10.14 H and a capacitance of 1 μF .A transformer is used to convert the alternating voltage from the 220V electrical network into 6V and a frequency of 50Hz. The indicated methodology can be widely used for developing seminar and laboratory exercises in physics.
