I'm glad it helped!! Good luck with your lab

it's so great to see experiments about theoretical things written in the textbook, plz keeping making more videos like this, I love it!

I was sick and missed two days of school, notes+lab, so i had no idea what to do this saved me so much!!!! Thank You

Great Video! Thanks for help. This is a very similar lab to the one I am taking right now and at Michigan State. I will be watching more!

Glad you enjoyed it!

I've never seen this done before. Very Kool!

great demo with very clear explanations and common errors highlighted. Thanks Sir.

thank you for having this my professor sucks balls! all the tenure couldn't give them a lick of sense in showing more freaking examples. your a life saver

Sir, I want to thank you for make this video. I was in the electric potential mapping lab today but during the lab, I was very confusing with the direction and polarity of the charges. All professor should demonstrate just like what you did. It really helpful!

you are the best, thank you sir!

very interesting idea! I'll have to try that. (would just a cookie sheet work too?)

thank you Sir - you are the best!!!

this is so helpful. much thanks!!!

Thanks!!

fantastic video!!!!!!

"Semiconducting paper" is not everywhere common. As a substitute consider using either A) a shallow tray filled with salty water, or B) a patch of damp earth outdoors. For A) you need to think of a way to mark the points and lines.

Wonderfull video !

Great music! What is the name of it? Also, excellent video. Prepared me for my upcoming lab :)

thank you so much!!

This was an amazing video ı understood damned physique for the first time!

Very clear.. thanks. Will use for my class

really nice

thank u very much i have understood everything about electric field and electric field lines they are real and exist

excellent :D

Thank you.

Nice demo.

شكرا جزيلا تجربو رائعة

amazing

Why must the force lines be perpendicular to the surface of a conductor with a static charge distribution?

Where do you get the metal bars you are using as parallel plates? I checked pasco and flinn among the usual places.

By cookie sheet I guess you mean aluminium foil. Aluminium has so low resistance that it is impractical to set up a 10 volt potential difference because the power supply would just go into current limiting. The foil surface develops a thin insulating oxide layer and the two conducting strips would need to be tight enough to pierce it uniformly.

Shouldnt the net electric field be moving towards the low end on the first experiment? Why does it move upwards towards the high end?

thank u so much

Thank you

I am from iit madras your explanation is good sir.

thank u very much. u r great teacher and your lecture ıs so cool, agian thanks.

Should do it with magnets with my son 5 yrs.

why is the reading in the origin, 5 volts? how do you determine the voltage reading in different areas or points? no access to these tools, online class sucks.

what is the importance of tightening screw, why does it matter so much? Theoretically, only a physical contact should be enough,isn't it?

كنت أرحب

Those with the magnet are not equipotential lines, but flux lines

ahemm u need atleast 1000 voltz D:/ atleast thats what we did in class anyways awesome wid :)

a sad ostim tek student was here

adamsn

congrats u picked the most boring way to show a magnetic field .
