## 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.
