    The screwdriver rule

    Slide 13 - Slide

    Slide 14 - Slide

    What you have to know
    • Current — the flow of electricity

    • Faradays law — current creates a magnetic field, changing a magnetic field creates current

    • The screwdriver rules

    Making an electro magnet
    • Solenoid
    • Core

    Slide 17 - Slide

    Slide 18 - Slide

    Solenoid

    Slide 19 - Slide

    Electro magnet schematic

    Slide 20 - Slide

    Slide 21 - Video

    Slide 22 - Slide

    what you have to know
    • An electromagnet creates magnetism using faradays law

    • How to make an electromagnet (solenoid + core + power source)

    • The strength of an electromagnet depends on the current in the solenoid

    Slide 23 - Slide

    Independent & dependent variables
    step 1 — Working independently for 5 minutes
    •  Read 7.4
    • Write down your own explanation of dependent and independent variables
    step 2 — Working together
    •  Compare your answers to your neighbours

    Slide 24 - Slide

    Independent variables
    • This variables is controlled

    •  This variable you make changes to

    • Cause

    • Controlled
    Dependent variables 
    • This variable is measured

    • This variable reacts to the changes you make

    • Effect

    • Reacts
