Eduscope India is a leading E-m By Helical Method (Long Solenoid Method)
Quick Answer: The E-m By Helical Method (Long Solenoid Method) apparatus has three major parts to measure the electron's specific charge (e/m) by the helical, long-solenoid method.
As a physics lab equipment India resource for modern-physics teaching, a standard solenoid of multi-turned layers is fitted on a wooden base, with 3000 turns, a winding length of 4.4 cm and a solenoid radius of 5.25 cm; the power supply for cathode voltage to the C.R.T. is provided with a high-resistance voltmeter of 1000V, along with a solenoid supply with coarse and fine control, measured by a 1.5-amp meter. It pairs naturally with EduScope India's E/m By Short Solenoid Method (Megnatron Methods) for comparing the two solenoid techniques.
