Im a bit confused about the indicator at 2:50 on why you can tell it is coming out of the page. What indicator is there that shows this. Thanks for the videos, they really help me in improving my grade
At 5:06 and 2:26 what do these dots represent for the field lines - different points of the lines? I didn't really follow, and the coils are the turns of wire? Thank you.
An x represents the back of an arrow and a dot represents the front on an arrow. The represents field lines pointed into and out of the page respectively.
YOU ARE AN IB LEGEND
You are amazing. Please keep making these -Portland, Oregon

Chris Doner Is there any way you could make a video on Alternating Current or Lenz's Law?
Philip Weiss
They are in the works.

Life saver
Your accent o.o I can't place it it sounds like a beautiful weird hybrid of canadian and australian and british o.o
Waiting for your video on 11.2 and 11.3! Thank you so much and please keep on making these videos! Kudos from Malaysia
They are posted now.
Very very helpful videos thank you!!!!
why cant the answer be B 14:15?
The flux through the coil would not consider the number of turns.
@@donerphysics oh thank you sir.
you taught me something 10x better than my actual physics teacher who calls herself an astrophysicist
Be respectful of your teachers and learn all that you can from them. The videos are a supplement that I am sure your teachers would encourage.

An x represents the back of a dart or arrow thus into the page. A dot represents the front of an arrow or dart, and hence, out of the page.

Hi I have a question what do you mean in 5:25 when you say that we will get an emf in the opposite direction?
emf is in the opposite direction when pulled out of field than when pushed in.
Great
