• Who is this content intended for?

  High-tier students only
• What happens when a wire carrying current is placed in another magnetic field?

  The wire experiences a force
• What is the motor effect?

  The interaction of magnetic fields causing motion
• How is the size of the force calculated?

  Using the equation: $F =$$BIL$
• What does the magnetic flux density measure?

  The strength of the magnetic field
• If a wire has a length of $2.5\text{ m}$, current of $1.5\text{ A}$, and magnetic flux density of $0.05\text{ T}$, what is the force?


  $0.19\text{ N}$
• What are the three factors that affect the size of the force?

  Magnetic flux density, current, length
• How do you use Fleming's left hand rule?

  Thumb, first finger, second finger at right angles
• What does the thumb represent in Fleming's left hand rule?

  The direction of motion (force)
• What happens if the conductor is parallel to the magnetic field?

  It will not experience a force
• What happens if the conductor is at right angles to the magnetic field?

  It will experience a force
• What is the significance of the motor effect in practical applications?

  It allows for the conversion of electrical energy to motion
