Motor Effect

    Cards (7)

    • What is motor effect and why is it used?
      -The motor effect is the effect at which a current carrying wire/conductor is put between magnetic poles.
      -The wire interacts with the magnetic field which exerts a force on both the wire and the magnetic field
      -This can cause the wire to move
    • How does the wire need to be positioned to feel the full force of the magnetic field and why?
      -The wire must be positioned at a right angle/90 degrees
      -This will allow for maximum interaction between the wire and magnetic field
    • Name the 3 factors that affect the force on the wire?
      -Increasing/decreasing current flowing through the wire
      -using stronger/weaker magnets
      -Positioning of the wire at 90 degrees is optimal
    • If the Magnetic field lines and Conductor are parallel what is the force acted upon the wire and magnetic field?
      -As they are parallel there is no force exerted on each other as the magnetic fields are not interacting
    • If the magnetic field lines are perpendicular to the conductor how strong will the force that acts on them be?
      -As they are perpendicular / 90 degrees the force that acts on them will be as strong as they can be not including the other factors that effect the force.
    • What can a wire with current flowing through it be called as?
      - A Current-Carrying Conductor
    • True or False A current carrying wire produces its own magnetic field?
      -TRUE
      the current carrying wire has a separate magnetic field which then interacts with another magnetic field to produce a force which is the motor effect
