The motor effect is when a current-carrying wire in the presence of a magnetic field experiences a force. A simple electric motor shows you that this is true.

My prediction is
P4-interaction forces(friction for walking) or GPE and KE
P5-Motors or differences between parallel and series circuits
P6-nuclear fission/fusion or radioactivity question with calculations

Crumple zones are also something worth revising
