Any predictions for tomorrows exam?
Has the motor effect come up as a 6 mark question?

What is the motor effect?

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.
Hopefully that comes up :erm: does anyone know what came up last year?

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 :smile:

Thank you, haven't seen last years probably the gold atom experiment then :wink:
