Current: conventional current flows + → − outside the cell — opposite to electron drift.
Field into/out of page: ⊙ out · ⊗ in.
Right-hand rule: thumb → current, curl → B; for force F = qv×B.
Induced EMF opposes its cause (Lenz): ε = −dΦ/dt.

Electromagnetism

Charge, field, current, flux — one connected machine. Drop charges and watch the field redraw, close a loop and read the current, sweep a magnet and see the EMF. Read V, I, B, Φ straight off the bench — ZAP!
