Review Identify these magnetic poles
Describe the shape of this field
South Left, North Right Field is straight in the middle and curved at the top and bottom
D) Direction of the force on a wire carrying current in a magnetic field
(Top View - Wire in a magnetic Field) Force on wire? Into, Out of Page?
Out of Page
3rd Left Hand Rule Why Left and not right?? 1) Draw Flux lines (N to S)
2) Left Thumb - direction of current
3) Four finger tips in direction of magnetic field
4) Palm shows direction of force on conductor
Figure 2 - Force on wire? Out or In?
