In this video I continue with my tutorials which cover the necessary vector calculus for classical electromagnetism which is pitched at university undergraduate level. Specifically I derive the Biot and Savart Law for magnetism. In many textbooks it’s noted as a law derived from experiment. However, it’s a consequence of Maxwell’s equations (as is everything in this regard too!). It requires some tricky vector calculus and that’s why it’s in my vector calculus tutorials and not my magnetostatics section.

I hope it’s of use!! Thank you for watching and I hope that this matches your requirements. Please feel free to provide feedback via comments and share with your friends.
