lab 1 Equipotential Lines, Electric and Magnetic Field Mapping

[@nik5132]

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

[@SinclairJohnston]

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

[@zhilongzhou1531]

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

[@jawpow000]

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!

[@sammirison7755]

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

[@SinclairJohnston]

Glad you enjoyed it!

[@FahSuper]

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!

[@Justalabrat]

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

[@sansastark4040]

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

[@SinclairJohnston]

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

[@MrCuddlyable3]

"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.

[@chunyang3506]

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

[@rajiprabhakaran9577]

Very clear.. thanks. Will use for my class

[@Revoluus]

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

[@AtlasReburdened]

Nice demo.

[@jainamsavla6253]

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

[@blessingmabasa9996]

you are the best, thank you sir!

[@kikibee31]

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

[@reubenwilliammpembe667]

thank you Sir - you are the best!!!

[@tgastrula6552]

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

[@MrCuddlyable3]

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.

fantastic video!!!!!!

[@Pedritox0953]

Wonderfull video !

[@miscapb]

this is so helpful. much thanks!!!

[@vineethkada2546]

I am from iit madras your explanation is good sir.

[@bilgeakaln6335]

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

[@SinclairJohnston]

Thanks!!

[@abdulaziz.a1179]

amazing

[@iny0ureyes]

thank you so much!!

[@ajc1233]

Thank you.

[@tonieleevillanueva2650]

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.

[@husniosman3532]

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

[@ayachinoureddine7056]

شكرا جزيلا تجربو رائعة

[@acdcgibsonmaniac]

excellent :D

[@anujagrawalsix]

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

[@AtlasReburdened]

Physical contacts are ohmic, they follow the rules of resistors, so if any minute patch isnt in contact it represents a parralel path that current can't take. That current distributes elswhere and you get irregularities in amperage which manifests here as dips and bulges in the measured voltage.

[@mehdimekhatria6589]

Thank you

[@profdderar]

thank u so much

[@mahu1203]

Should do it with magnets with my son 5 yrs.

[@noberom7054]

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

[@selimcoruk2400]

hocam emeğine sağlık

[@cooltop1]

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

[@SinclairJohnston]

كنت أرحب

[@moon_iq]

a sad ostim tek student was here

[@AliEmir123]

adamsn

[@booboo3690]

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