Specification References

6.11 appreciate that there is a force on a charged particle when it moves in a magnetic field as long as its motion is not parallel to the field
6.12 recall that a force is exerted on a current-carrying wire in a magnetic field, and how this effect is applied in simple d.c.electric motors and loudspeakers
6.13 use the left hand rule to predict the direction of the resulting force when a wire carries a current perpendicular to a magnetic field
6.14 recall that the force on a current-carrying conductor in a magnetic field increases with the strength of the field and with the current

Starter

Show them the wire hanging between the two poles of magnet and switch on current. Let them discuss what happens.
Reverse polarity, direction of current and let them analyze what happens.
Have ready one of the little motors and tell them that they will have to be building one themselves

Use the 'Electric Bell' and 'Relays' worksheet. Pupils should stick them in their books and use them to fully explain how they work.

electric bell demo, different relay demos, circuit breakers RCD's, coils, power supplies, plotting compasses.
