Amp-re's Law: Crash Course Physics #33
video description
I should be H (field strength)
Also Ampere did not explain WHY magnetic fields can atttract or repel.
He developed theories based on that OBSERVED fact.

Crash Course, I believe there is a problem with the direction of which the magnetic field is going at 5: 16. If the current of the wire is pointing up, shouldn't the magnetic direction be pointing counterclockwise? I hope you can fix this. Thanks

unless you mean electron flow direction (which would only complicate stuff) the field should be turning in the opposite directions. It's called right hand rule because you use your right hand, Seems like you used your left.

Apart from the errors at 5: 15 and 5: 25, at 6: 26 the formula does not include the length as the denominator on the right hand side but it's ok as long as you know that n is the number of turns per unit length.

the theta is first mentioned as the angle between the B-field and current (2: 09) and then later on mentioned as the angle between B-fields at different points of the loop. I don't know which one is correct

Why is there greater length in the pauses within her sentences then there are between the sentences themselves? This editing makes the production feel abnormally and unnecessarily rushed.

At 7: 20, the forces are shown correctly, yet actually result in counter-clockwise motion. The clockwise motion at 7: 30 came from the unexplained reverse of the magnetic field.

At 2: 08 it's written that theta is the angle between current and magnetic field, shouldn't it be the angle between the element ds and the magnetic field?

Honestly everything that came out of her mouth after the mistake at 5: 14 I couldn-t even believe her, correct the mistake you-re just losing credibility

why you make things easy. taught us as our tutors did(4 Year)but i respect them still. I understand now the Ampere's law in a good and effective way.
