Faraday's law Physlet-Based Curriculum

These examples of curricular material appear in Section 9.7. Follow a link on the left to go to the individual Physlet problems found in that section and several bonus problems only available on this CD. Below is a brief description of each animation.

Chapter Problems:

9.7.1: The animation shows a top view of four wires and a galvanometer.  During the time interval t=2 s to t=8 s a magnet is slowly pushed completely through  the rectangle from the bottom.  

9.7.2: A loop of wire travels from the right to the left through an inhomogeneous magnetic field. (The green line is at x=0 is for your reference.) The induced emf in the loop is shown in Volts in the animation.

9.7.3:  A loop of wire moves to the right through a magnetic field (a positive magnetic field is out of the screen) that abruptly goes to zero at x=0. 
9.7.4: The above animation represents a moving wire loop in a changing magnetic field.  9.7.5: A transformer is connected to a wall socket as shown above. The graph shows the primary voltage Vp (black) and the secondary voltage Vs (red).   

 

Additional Problems:

9.7.ap 1:  A loop of wire sits in a time varying magnetic field (a positive magnetic field is out of the screen). You may drag the loop around the animation.  9.7.ap 2:  A loop of wire is to the right of a wire that runs up the computer screen (a positive magnetic field is out of the screen). 
9.7.ap 3:  A transformer is connected to a wall socket as shown.  You can read component values by placing the mouse over a component.
