| So what happens when a Wire is placed between Opposite Poles of a Magnet? | -The Wires Magnetic Field and the Bar Magnetics Field interferes, and makes a Force on the Wire. |
| In an Exam, if the Current had an X on it, what does it mean? | The Current's or Wire's Direction would be going Towards the Paper
If it was a Dot, the Wire is coming Towards you |
| What angle does the Wire need to be to Experience the Full Force? What about the Opposite? | It has to be at 90 degrees. For the Opposite, it has to run Along the Magnetic Field. No Force will be felt. |
| What factors can change the Force on the Wire, and the Magent? | The Current, or the Magnetic Flux Density Increases |
| How can the Direction of the Force Change [Magnetism] | It has to be in Relative of the Magnetic Field, and the Direction of the Current.
Change one of those Directions, and the Force will change as well. |
| How can you show the Direction of the Force using a Practical? | Put some Rails, that is Connected in a Horseshoe Magnet.
Add Current in the Rails, and then place a Bar on top of the Railings.
The Bar can Complete the Circuit, meaning a Magnetic Field can be Produced
The Force made, moves the Bar around. |
| What is Fleming's Left Hand Rule? | This is the Rule to find the Direction of a Force, on a Current carrying Wire
With you left hand, Point the First Find [Index] in the Direction of the Magnetic Field Lines...
The Second Finger [Middle Finger] in the Direction of the Current...
And the Thumb will then Point in where the Force is going to act on |
| What Equation can you use to find the Force on a Wire that is Carrying Current | Force on a Conductor = Magnetic Flux Density x Current x Length
carrying a Current
Symbols [F] = [B] x [I] x [L]
or
Measurements [N] = [T] x [A] x [m] |
