Good work!
Going step by step helps a lot. I like how you do one operation on each line so I can see how you get to the final answer.
That’s great to hear. I find fewer mistakes are made if you take step by step.
Why this is in my recommended I don’t know
I hope you enjoyed it or that it was helpful at least.

We see the oscillation, it is the quantization that we can't see.
That’s too fast for someone’s hand lol
Indeed it is! Thank you for watching and commenting!
Note for part b, when I calculated the power I did square the voltage but I missed writing down the exponent.
We usually only talk about the direction of induced current as opposed to the direction of induced emf. The induced emf has a polarity that drives the induced current around the loop though, and it will be in the same direction as conventional current meaning out of the positive "terminal" around the loop and back into the "negative" terminal.
Is n hat a unit vector that’s perpendicular to the plane of the area?
Yes, the hat notation makes it a unit vector which means it has a magnitude of 1 unit and n is the letter we typically use for the normal vector. The normal vector is a vector that is perpendicular to something. So in this case it is a vector that is perpendicular to the plane of the area. Great question! Thank you for asking and for watching!
Note that to find 3 unknowns we need exactly 3 equations.
