The Electromagnetic Solenoid Cannon

 

Michelle Bolton, Mike de Jong, Chris Warren, Dept. of Mechanical Engineering, University of Ottawa

 

 

 

 

 

OBJECTIVES

 -          Utilize the energy storage capabilities of capacitors to convert a current into an electromagnetic field by way of a coil of wire

(creating a solenoid)

-          Use the electromagnetic field created to displace a magnetic object placed within the solenoid to a location outside the solenoid

-          Demonstrate the effects of the solenoid by building a model cannon using the solenoid as a cannon barrel

-          Control the rotation of a bipolar stepper motor through the use of an Arduino Duemilanove microcontroller and a potentiometer

-          Create a horizontal positioning system by integrating the bipolar stepper motor control with the solenoid cannon
