The Motor Effect

1. 1What is the motor effect?

   1. AWhen a current-carrying wire is placed between magnetic poles and the magnet and wire exert a force onto each other. This causes the wire to move.
   2. BThe induction of potential difference in a wire which is moving relative to a magnetic field.
2. 2You can change the speed of the motor by changing the current?

   1. AVerdadeiro
   2. BFalso
3. 3What is the name of the rectangular coil used in a motor?

   1. AArm
   2. BCommutator
   3. CArmature
   4. DSpring
4. 4How can you increase the turning effect?

   1. AIncrease the current
   2. Bincrease the temperature
   3. Cuse a stronger magnet
   4. Dmove it further from the magnet
   5. Eensure that the wire is perpendicular to the magnetic field
5. 5Force= magnetic flux density x current x length

   1. AVerdadeiro
   2. BFalso
