Electromagnetism Exercises Physlet-Based Curriculum

These examples of curricular material appear in Section 7.2 of Physlets. Follow a link on the left to go to the individual Physlet problems found in that section. Below is a brief description of each animation.

Chapter Exercises:

7.2.1One fixed charge and one “test” charge is shown in each animation. The fixed charge is labeled by an “f” and the test charge is labeled by a “t”. There are three animations depicted.

7.2.2You are asked to calculate the electric field due to a charge filament as shown in the animation. You are given three different detectors and three different viewpoints: intermediate distance, very close, and very far from the filament 

7.2.3:  The animations represent a typical bar magnet with a North and South pole. You may double click anywhere inside the animation to add a magnetic field line. You may also add a compass by clicking the “Add Compass” link.
7.2.4The above animations represent two typical bar magnets each with a North and South pole. The arrows represent the direction of the magnetic field.   7.2.5A cross-section of a circular wire loop carrying an unknown current is shown above.  You may also add a compass by clicking the “Add Compass” link. 7.2.6A cross section of three wires carrying unknown currents is shown above.  You can double-click anywhere inside the animation to draw a magnetic field line. You may also add a compass by clicking the “Add Compass” link.
7.2.7A cross section of three wires carrying unknown currents is shown above. You can click-drag the wires and the black arrow represents the force experienced by each wire.  7.2.8A loop of wire travels from the right to the left through an inhomogeneous magnetic field as shown in the animation. The induced emf in the loop is shown in Volts as is the direction of the induced current.
