Task 1
Increase the current flowing through the motor. How does the speed of the motor change?The motor rotates at a higher speed.
Task 2
Increase the magnetic field strength. How does the speed of the motor change in this case?The motor rotates at a higher speed.
Task 3
Increase the number of turns in the coil. Again, find the out how the speed of the motor will change.The motor rotates at a higher speed.
