E M By Thomson Method

Description

E/m by Thomson’s Method (Bar Magnet Method with CRT) | Zodiac Overseas

Product Description:

The E/m Thomson’s Method Apparatus (Bar Magnet Method with CRT) is a complete experimental setup for determining the charge-to-mass ratio (e/m) of an electron. The setup consists of a high-quality Cathode Ray Tube (CRT) where the electron beam is produced and observed on a fluorescent screen. The deflection of the beam under the influence of an electric field is balanced by the magnetic field generated using bar magnets, allowing accurate measurement of the e/m ratio.

This apparatus is widely used in modern physics laboratories for undergraduate and postgraduate studies in electron dynamics.

Key Features:

• High-quality CRT (Cathode Ray Tube) with fluorescent screen
• Pair of bar magnets for generating uniform magnetic field
• Precision power supply unit with controls for CRT operation
• Scale arrangement for accurate deflection measurement
• Rugged, reliable, and easy-to-use design for lab use

Supplied Apparatus:

• CRT with mounted scale arrangement
• Bar Magnet Set (2 pcs)
• Regulated Power Supply Unit
• Wooden/metal stand for proper alignment
• Instruction Manual with theory, procedure, and calculations

Applications:

• Measurement of e/m ratio of electron
• Study of electron beam deflection in electric and magnetic fields
• Fundamental demonstration in modern physics and electron dynamics
• Useful for colleges, universities, and research laboratories

Advantages:

• Includes CRT for clear observation of electron beam
• Accurate and reliable measurement method
• Durable and complete experimental kit
• Widely used in educational institutions & physics research labs
