6.7.2 The motor effect (Higher & Foundation)

State examples of how the magnetic effect of a current can be demonstrated and explain how a solenoid arrangement can increase the magnetic effect of the current
Draw the magnetic field pattern for a straight wire carrying a current and for a solenoid (showing the direction of the field)
HT ONLY: State and use Fleming's left-hand rule and explain what the size of the induced force depends on
HT ONLY: Calculate the force on a conductor carrying a current at right angles to a magnetic field by applying, but not recalling, the equation: [ F = BIL ]
HT ONLY: Explain how rotation is caused in an electric motor
