    Do you guys have any predictions for the physics 6 markers? It probably won't be Herschel and Ritter because that came up last year, didn't it?
    Generating Electricity the one with slip rings and carbon brushes.

    I actually predicted correctly on Nitrogen Cycle for Biology and Liquid Paraffin for Chemistry

    In industry, electricity is generated by spinning a coil of wire in a magnetic field.The carbon brushes act as contacts with the slip rings, so that the current can always flow from the coil to an external circuit. Its basically just moving a magnet with coils on through a magnetic field to make electricity - you'll probably have to revise how to change the current too eg. spinning it faster, more coils = bigger current

    I thought that was p2? Why would p2 come into p1?

    If ur talking about the carbon brush and slip rings, I didn't know about that as well and won't bother learning it haha.

    electromagnetic induction came up on last years paper
    evidence: explain how this current is induced in the coil in the model.
