Bernard Siachingoma, John Madhombiro

Abstract: Transistors occupy a crucial position in technological advancement. They are used as power switching and signal amplifiers, as sensors in oscillating circuits. In this study the effects of magnetic fields on the operation of the 2BC109B bipolar junction transistor were investigated. The current-voltage (I-V) characteristics were analysed. The research showed that the performance and output characteristics of the transistor are affected by the presence of the external magnetic field and its intensity. The study confirmed amplification for low values of the magnetic field but showed that very intense fields cause failure.
