... characteristics: a) the magnetic field is either zero or has a constant value on segments of the path b) the magnetic field is either parallel or perpendicular to the path. 2. Determine the net current that penetrates the area bounded by the closed path. 3. Multiply B by the length of each segment o ...

... and the common lead (black mini-grabber) to ground. Adjust the voltage at VCollector to 3 Volts using Pot#4 (10k). The adjustment is as follows: VCollector > 3 volts – This means there is not enough current flowing through the magnet and the transistor to produce a large enough magnetic field to s ...

... Exploration – Motors and Generators: 50 minutes – Group Lab Work The students build motors according to the apparatus described in the Analysis stage. It takes them a lot of time to build a well balanced motor, but their motors will work much better if carefully built. They explore how to determine ...
