Lorentz Force e/m Apparatus for Advanced Physics Lab

The Lorentz Force e/m Apparatus for Advanced Physics Lab is designed to help students study the fundamental principles of electromagnetism through direct observation and measurement. The apparatus demonstrates the Lorentz force acting on charged particles moving through electric and magnetic fields, providing a clear understanding of particle motion and electromagnetic interactions. During the experiment, an electron beam is generated, accelerated, and exposed to controlled electric and magnetic fields. By observing the resulting beam deflection, students can investigate the effects of the Lorentz force and analyze the motion of charged particles. The apparatus also enables determination of the electron charge-to-mass ratio (e/m), one of the most important physical constants in atomic physics. Its robust construction, user-friendly operation, and reliable performance make it well suited for physics laboratories in colleges, universities, and technical institutions. The apparatus offers valuable hands-on experience in experimental techniques, measurement procedures, and data analysis. Manufactured by Atico Export India.
