Return to 6 Magnetism – Part A “Units”

6 Magnetism – Part C “Solenoids and Fields”

Syllabus Aims…

6.8 know that an electric current in a conductor produces a magnetic field around it

6.9P describe the construction of electromagnets (Triple)

6.10P draw magnetic field patterns for a straight wire, a flat circular coil and a solenoid when each is carrying a current (Triple)

6.11P 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 (Triple)

6.12 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.

6.13 use the left-hand rule to predict the direction of the resulting force when a wire carries a current perpendicular to a magnetic field.

6.14 describe how the force on a current-carrying conductor in a magnetic field increases with the magnitude and direction of the field and current.
