Magnetic Fields Physlet-Based Curriculum

These examples of curricular material appear in Section 9.6. 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:

9.6.1: The above animations represent two typical bar magnets each with a North and South pole. The arrows represent the direction of the magnetic field.  

9.6.2: A cross-section of a circular wire loop carrying an unknown current is shown above.   The arrows represent the direction of the magnetic field.  

9.6.3:  A cross section of three wires carrying unknown currents is shown above.    You can click-drag the wires but this will erase any field line that you have drawn.
9.6.4: The above animations represent two typical bar magnets each with a North and South pole.  A wire is placed between the magnets and a current that comes out of the page can be turned on.  9.6.5: A wire with current flowing through it perpendicular to the page is shown. Also shown is a choice of two detectors that displays the integral, 9.6.6: A cross-section of a two circular wire loops carrying the exact same current is shown above.  You can click-drag to read the magnitude of the magnetic field. 

 

Additional Problems:

9.6.ap 1:  A wire carrying an unknown current is shown above. An external magnetic field that has constant magnitude and direction is applied to the top half of the simulation.  In addition, there is the magnetic field produced by the current in the wire.   9.6.ap 2:  A wire carrying an unknown current out of the page is shown above.  You may also double-click in the animation to create a field line. Assume that the distance shown is in cm and B is shown in milli Tesla.
9.6.ap 3:  Two wires with current flowing through them perpendicular to the page are shown. Also shown is a choice of two detectors that displays the integral, .   9.6.ap 4:  A magnetic field  is shown in the animation along with a loop (the position is given in meters and the magnetic field in milli Tesla). 
9.6.ap 5: A magnetic field  is shown in the animation along with a loop (the position is given in meters and the magnetic field in milli Tesla).
