  1. 28 February2014 Motoring Learning Objective To investigatemagnetic fields. Some • Explain how Fleming’s left-hand rule is used to predict the direction of the force. (A/B) Most • Describe the effect of reversing the current and/or the direction of the magnetic field.. (B) All • Explain why a current-carrying straight wire placed in a magnetic field can move.(C) • All – Explain why a current-carrying straight wire placed in a magnetic field can move(C) • Most - Describe the effect of reversing the current and/or the direction of the magnetic field. • Some - Explain how Fleming’s left-hand rule is used to predict the direction of the (A/B)

  2. To investigate magnetic fields. Starter Magnetism quiz • All – Explain why a current-carrying straight wire placed in a magnetic field can move(C) • Most - Describe the effect of reversing the current and/or the direction of the magnetic field. • Some - Explain how Fleming’s left-hand rule is used to predict the direction of the (A/B)

  3. To investigate magnetic fields. Practical Follow the instructions on the practical worksheet. • All – Explain why a current-carrying straight wire placed in a magnetic field can move(C) • Most - Describe the effect of reversing the current and/or the direction of the magnetic field. • Some - Explain how Fleming’s left-hand rule is used to predict the direction of the (A/B)

  4. To investigate magnetic fields. • All – Explain why a current-carrying straight wire placed in a magnetic field can move(C) • Most - Describe the effect of reversing the current and/or the direction of the magnetic field. • Some - Explain how Fleming’s left-hand rule is used to predict the direction of the (A/B)

  5. To investigate magnetic fields. There are four ways of increasing the strength of an electromagnet Coil – more coils in the same volume of space Core – put a soft iron core into the coil Current – increase the current flowing Curvature – wind the coils tighter on the core • All – Explain why a current-carrying straight wire placed in a magnetic field can move(C) • Most - Describe the effect of reversing the current and/or the direction of the magnetic field. • Some - Explain how Fleming’s left-hand rule is used to predict the direction of the (A/B)
