Connect the positive wire of the 9V battery clip to the drain pin of the mosfet and the negative wire to the dc motor.

Connect the Potentiometer

Connect the left pin of the potentiometer to the drain pin of the mosfet, the middle pin to the gate pin of the mosfet, and the right pin to the negative wire of the 9V battery clip.

The Last Connection

Finally connect the source pin of the mosfet to the other pin of the dc motor. Now just plug in the 9V battery and we are done.

Testing

If you connect everything correctly than if you turn the potentiometer anticlockwise the motor will spin faster and if I turn the potentiometer anti clockwise the motor will slow down.
