The Circular motion is one of physics learning topic that has number of physics parameter. There are angular velocity and angular acceleration. They are can be calculated and measured. The aim of this research is to measure angular velocity and angular acceleration using logger pro magnetic sensor on the top of the propeller by varying the speed fan. There is a magnet bar that is attached on propeller top surface. The magnetic sensor is placed on the top of it. The distance is 0.01 meter. The motion of the magnet bar follow the circular motion of the propeller. Hence, circular motion can be tracked by plotting the magnetic field intensity over time. The maximum angular velocity of speed 1, speed 2, speed 3 were 5.709 rad/s, 10.467 rad/s, and 10.467 rad/s, respectively. The maximum angular acceleration of speed 1, speed 2, speed 3 were 0.594 rad/s 2 , 2.492 rad/s 2 , and 2.492 rad/s 2 , respectively. The measuring of angular acceleration for each speed are obtained by value that are different. This is due to wind speed and the changed rotation that are different.
