JaincoLab E M Apparatus Instrument sets measure the charge-to-mass ratio (e/m) of the electron in physics laboratories using classical methods. Each method has its own model: Thomson's bar-magnet method (JA-EMA-1065), the helical or solenoid method (JA-EMA-1066), the short-solenoid or magnetron method (JA-EMA-1069) and magnetic focusing (JA-EMA-1070), alongside a stabilised power supply (JA-EMA-1068) for the Millikan oil-drop experiment.
Last updated: October 2026.
What is E M Apparatus Instrument?
E M Apparatus Instrument is a range of physics apparatus for measuring the charge-to-mass ratio (e/m) of the electron using classical methods — Thomson's bar-magnet method, the helical/solenoid method, the short-solenoid (magnetron) method and magnetic-focusing — along with a stabilised power supply for the related Millikan oil-drop experiment.

| College / University | Modern-physics and electromagnetism coursework |
| Research Laboratory | Reference apparatus for classical e/m measurement methods |
Frequently Asked Questions
Q: How does E M Apparatus Instrument differ from Nuclear Physics?
A: E M Apparatus Instrument covers classical electron charge-to-mass (e/m) measurement methods using magnetic deflection and focusing. Nuclear Physics instead covers radioactivity and nuclear-counting apparatus, such as G.M. counters.
Q: Is the power supply JA-EMA-1068 an e/m measurement set?
A: No. JA-EMA-1068 is a stabilised power supply for the Millikan oil-drop experiment. The e/m ratio itself is measured with one of the four method-specific sets: JA-EMA-1065, JA-EMA-1066, JA-EMA-1069 or JA-EMA-1070.
