Inductive Charging using an Electroscope

This shows how to do inductive charging. It's demonstrated using an electroscope, a piece of vinyl taken from unused window blinds and a drinking glass... oh and my finger! This video was made in response to a question asked in the comments for my first video about how to make an electroscope. Be sure to have a look at the "How to make an Electroscope" video too at:

THANK YOU this helped me so much for my ap physics class!! your awsome!! this was such a good way to demonstrate it!!

@MrTroy354 You're very welcome! Thank YOU for the feedback!

[IRmShaDe]

what materials did you use to rub together to transfer the charges? thanks in advance

[RimstarOrg]

@IRmShaDe I rubbed a normal drinking glass and a piece of vinyl cut out from window blinds that you roll up. Wash the glass thoroughly first with soap and hot water and rinse thoroughly to get any grease off. The rubbing takes advantage of the triboelectric effect. See my video "Triboelectric effect/series or triboelectricity" for which materials work and why. There's an annotation at the end of this video to click on for the triboelectric video and a link in the comments.

Excellent video and explanation. Thank you.

@AGuyWhoMakesVideos That's sort of a strange question. My guess is somewhere in your course material or lecture 3 specific things were listed, so my answer may be different. But here goes anyway: to detect a net charge on an object, to measure the relative magnitude of charge on different objects, and to determine the sign of the net charge on an object (using techniques like in this video.)

If someone would mind answering this, I really need to know the answer to it:

What are the 3 purposes of an electroscope?
