- Lesson Plan →Objectives, pacing and practice, built from this lesson's brief.
- Guided Notes →One page your students fill in and keep.
- Exit Ticket →Three items at the end of class. No student accounts.
- Re-teach →After an exit ticket: who missed what, and what to do tomorrow.
- Homework →Assign practice; it grades itself.
"The magnetic force on a moving charge is F = qvB sinθ, where θ is the angle between v and B. The direction of the magnetic force is given by the right-hand rule."
"The magnetic force on a current-carrying conductor is F = BIL sinθ, where L is the length of the conductor and θ is the angle between the current direction and B."
