About E/M BY MAGNETIC FOCUSSING
Specification:
E/M BY MAGNETIC FOCUSSING
Objective:
To study charge of an electron by using Magnetic Focusing method.
Features:
Kit comprises of High voltage Power Supply with intensity, focus X, Y deflection & Solenoid current controls.
Two meters provided for acceleration voltage & for solenoid current controls.
Accurate Measurement of e/m Ratio
This apparatus facilitates the direct and precise measurement of the electron's charge-to-mass ratio using the magnetic focusing method. The fluorescent screen makes the electron beam path clearly visible, while factory calibration ensures reliable readings during experiments.
User-Friendly and Safe Design
Intuitive panel-mounted analog meters and separate controls for voltage and coil current simplify the operation for students. Safety is enhanced with a fuse-protected power supply, allowing secure experimentation under supervised laboratory conditions.
Robust Construction and Educational Compliance
Manufactured from stainless steel with a durable powder-coated finish, the unit meets standard engineering lab requirements. Its compact, benchtop design and included accessories make it ideal for academic demonstration and single-student practical use.
FAQ's of E/M BY MAGNETIC FOCUSSING:
Q: How does the E/M by Magnetic Focusing apparatus measure the electron's e/m ratio?
A: The apparatus uses a sealed glass tube containing an electron gun and adjustable Helmholtz coils to produce and control a focused electron beam. By varying the coil current and tube voltage, users can observe the beam's focusing and radius on a fluorescent screen, allowing calculation of the electron's e/m ratio through direct measurement.Q: What is the recommended usage process for this apparatus in a laboratory setting?
A: First, connect the apparatus to the standard 220V AC mains using the supplied power cord. Adjust the tube voltage and coil current using the designated panel controls. Observe the electron beam focus on the internal fluorescent screen, and use the analog meters for accurate readings, following the steps in the included operation manual.Q: When should the fuse be replaced in the power supply unit?
A: The fuse should only be replaced if the instrument stops powering on, indicating a potential electrical overload. Always turn off and disconnect the unit before replacing the fuse. A spare fuse is included for convenience and safety.Q: Where can the E/M by Magnetic Focusing apparatus be used?
A: The apparatus is intended for benchtop use in educational and engineering electronics laboratories. Its design complies with standard academic laboratory requirements and is suitable for single-student experiments or classroom demonstrations.Q: What are the benefits of using magnetic focusing with Helmholtz coils in this experiment?
A: Magnetic focusing with Helmholtz coils enables precise control over the electron beam's path, allowing accurate observation and measurement. This enhances experiment reproducibility and helps students better understand the behavior of charged particles in a magnetic field.Q: How does the fluorescent screen aid in electron beam visibility?
A: The built-in fluorescent screen glows brightly where struck by electrons, making the otherwise invisible electron beam path easily observable and allowing clear determination of beam radius and focus points for measurement.
