Active Physics: Electromagnetic Induction

This activity required the analyzation of the magnetic flux/EMF produced when certain frequencies, area, and magnetic field are manipulated. This picture represents no rotational frequency.

Here the frequency changed as the area changes. 

In the purple is the response to a series questions that represent the EMF and magnetic flux changes with changing conditions. Questions (1-13)

Active Physics: Magnetic EMF

Here the red bar above is moving creating a induced EMF. This assignment analyzes the motion of the bar and its effects on the magnetic flux and induced EMF. Question (1-8) address these changed and they are affect by the motion of the bar.

Measuring Inductance

Connecting a solenoid to a function generator in series with a resistor 149 Ohm resistor  we can use a oscilloscope to determine the inductance of the solenoid. We can compare this experiment value with a calculated value  and a value from the detector. 

Find the time interval we experimentally determined the inductance to be 0.0116 h. Doing calculations above we determined the theoretical value to be 0.0078h and with a meter we determined the measured inductance to be 0.00739h.
