    Maximum Voltage To Apply To An Air core Electromagnet

    Yes I know what you mean by how inductors work as regards acting as capacitor and thereby multiplying voltage during back EMF process. But that is not what my request is about now. I need your help by interpreting how to do what you said that "If you disconnect the coil while a current is...

    Maximum Voltage To Apply To An Air core Electromagnet

    Thank you all for your reply so far. There is no way for me to get the temperature rating of the coil as I bought it in Spool from a local electronic spare part store her in Nigeria. But I after I finished winding the coil and supplied 500vdc (using capacitor voltage doubler) to it via the wall...

    Maximum Voltage To Apply To An Air core Electromagnet

    Sorry people, I'm wrong by saying the Core of the Solenoid is 120mm in height and 13inches in Diameter. What actually mean to say is the Air core Windings is 120mm in height and 13inches in Diameter.

    Maximum Voltage To Apply To An Air core Electromagnet

    Hello everyone. I am glad I came across this science oriented Forum site. I actually get there from Google and what I am deeply curious to know about is the amount of Maximum Voltage my 3.5kg Air Core Electromagnet can bear. The Core of the Solenoid is 120mm in height and 13inches in...
