E-m By Thomsons Method (Bar Magnet Method)
Product Code : EL-LE-12137
Eduscope India is a leading E-m By Thomsons Method (Bar Magnet Method)
Quick Answer: The E-m By Thomsons Method (Bar Magnet Method) apparatus measures the specific charge (e/m) of the electron by Thomson's bar-magnet method, using the controlled bending of a beam of high-speed electrons in a magnetic field.
As a physics lab equipment India resource for modern-physics teaching, the apparatus has been perfected so this fundamentally important measurement can be carried out with good accuracy, giving students the stimulating experience of actually measuring the ratio of an electron's charge to its minute mass. It pairs naturally with EduScope India's E/m By Short Solenoid Method (Megnatron Methods) and E-m By Helical Method (Long Solenoid Method) for a complete set of e/m determination techniques.
