level questions: Magnetic Forces

QuestionAnswer
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 CurrentForce 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]
