Motor Effect

• 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
