Induction and AC motors

Since a current bearing wire has a magnetic field, placing the same wire in an external magnetic field will mean it will experience a force. This is known as the motor effect. See Resources for using a current balance which examine the motor effect 
Induction and AC motors

In this video I discuss AC motors, in particular, synchronous motors. I then lead on to the physics behind induction motors

There are a number of ways we can explore this concepts further.
One aspect of most high school physics course on kinematics, is that they only concern themselves with constant acceleration. In reality however, acceleration, like displacement and velocity, can chance with respect to time.
Velocity is the rate of change of displacement. Unit: m/s^{2}
Acceleration is the rate of change of velocity.
So what is the rate of change of acceleration?
The answer to that is the jerk. So slope of the acceleration vs time graph is the jerk. Unit: m/s^{3}
We can go further. What is the rate of change of the jerk?
Well it's the snap. Unit: m/s^{4}
Can we go further? Yep. The rate of change of snap is the crackle. Unit: m/s^{5}
I think you can guess the next one.

 pHET graphing animation  this interactive from the University of Colorado pHet team is a great way to demonstrate the relationship between motion and its graphical analysis. That why I used it in my video. At this time its Java based so will only work on PC/Mac
