Introduction to Speaker Magnets Speakers are intricate devices that play a crucial role in audio technology by converting electrical energy into sound. The type of magnet used in a speaker significantly influences its performance and sound quality. Classification of speakers can be based on the magnetic circuit structure (internal magnet vs. external magnet) and the principle of sound generation (dynamic, electromagnetic, piezoelectric, and electrostatic). Evolution of Speaker Magnet Technology Initially, dynamic speakers relied on electromagnetic drive mechanisms due to the

Introduction Magnetic field measurement is a crucial aspect in various industries, from electronics to healthcare. A Gaussmeter, also known as a Tesla meter, stands as the primary tool for this purpose. This guide delves into the workings of the widely-used Japanese KANETEC Gaussmeter and explores the principles and applications of magnetic field measurement. The Hall Effect: Core Principle Behind Gaussmeters The Gaussmeter operates based on the Hall Effect. When a current-carrying conductor is placed in a magnetic field, a transverse
