Electro-magnetism

This week we have been refreshing our memories about magnetic fields around magnets and current carrying conductors. This diagram of the magnetic field associated with a Solenoid uses the "dart analogy" this time used to show direction of conventional current (positive to negative) in the wire.
 
I hope you've all done your homework or as our Brazilians might say "dever de casa". The homework of course was to finish activities 17a and 17b.
