Physics 11th Grade: Ampere Force
I was asked to explain the Lorentz force and how it's derived. But since it's derived from the Ampere force, I decided to cover it right away. It seems pretty straightforward. My apologies for the "left hand" approach; that's just how I see things. I'll post problems on this topic on specclass.ru. Stay tuned for updates in my VKontakte group, on Facebook, and on my Twitter.
