6.2.1 Know that an electric current in a conductor produces a magnetic field around it
6.2.2P Describe the construction of electromagnets
6.2.3P Draw magnetic field patterns for a straight wire, a flat circular coil and a solenoid when each is carrying a current
6.2.4P Know 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
6.2.5 Understand why 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
6.2.6 Use the left-hand rule to predict the direction of the resulting force when a wire carries a current perpendicular to a magnetic field
6.2.7 Describe how the force on a current-carrying conductor in a magnetic field changes with the magnitude and direction of the field and current
Increased magnitude of current increases force
Increased magnitude of magnetic field increases force
Changed direction of current changes direction of force
Changed direction of magnetic field changes direction of force
