- buiding electric mototrs
Contents
Specification References
- 6.11 appreciate 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
- 6.12 recall that 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 recall that the force on a current-carrying conductor in a magnetic field increases with the strength of the field and with the current
Starter
- recall that a current-carrying wire placed in a magnetic field, experiences an elecromagnetic force on it
- the direction of the electromagnetic force acting is given by the Fleming's left hand rule
