Question 1

What must occur for the motor effect to happen?

  • A current must flow and be parallel to the magnetic field.
  • No conditions are needed.
  • A current must flow and be in an external magnetic field.
  • Only a magnetic field is necessary.

πŸ’‘ Hint: Remember the conditions we've discussed.

Question 2

True or False: The maximum force occurs when the current and magnetic field are perpendicular.

  • True
  • False

πŸ’‘ Hint: Visualize the angle and its measurement.

Challenge Problems

Push your limits with challenges.

Question 1

Consider a situation where you have a wire at a 45-degree angle in a magnetic field, causing a weak force. Calculate the maximum potential force if the wire is rotated to 90 degrees.

πŸ’‘ Hint: Refer to the basic physics equations of force in magnetic fields.

Question 2

Design a motor using the principles of the motor effect and describe how you would ensure it operates efficiently.

πŸ’‘ Hint: Think about the variables we discussed in connection with real-world motors.
