This is a power point presentation which can be used link the following topics:
Current electricity, electromagnetism, permanent and temporary magnets, effect of impurity atoms in Al Ni Co magnets, magnetic fields, the motor effect and the action of heat on magnets.
If you have an old Teltron e/m deflection tube then even better because a demonstration allows students to see the effect of a magnetic, (and if time, electric field), on a stream of electrons.

Thanks for viewing: I guess the equipment is difficult to access at the moment May 2020 there's video on YouTube using coils to deflect the beam but to demonstrate what's in the power point, if you have a tube, just use a simple bar magnet
