Throwback To shake it experiment

Earlier this semester we realized an experiment that involved shaking.

Through the experiment, we performed multiple tasks that surrounded the concepts and most notably the relationships between electromagnetic flux and Voltage. To tackle the experiment, we needed several items which consisted of :

Flashlight (Composed of magnet and coil)
NXT
NXT Adaptor
Labview VI
Process:

We started the habitual Labview software, later we attached the metal part of the flashlight’s coil wire to the voltage probe.
Subsequently connected the NXT to the Computer. We were then instructed to vigorously agitate the flashlight in a 30s interim and to note the sum square of the voltages.
Shake object whilst registering number of shakes for accurate data
Calcutta using Microsoft Excel the Sum square of our new data
Repeat activity twice in order to further observe the data and it’s pattern.

Data recorded: shake it

 

Observations:

Initially, the magnet within the flashlight is at rest so there is no large fluctuations within the data. With the data being concurrently recorded, we observe that as we begin to shake the probe,it emits a superior amount of voltage. Faraday’s law also states that the voltage is directly proportional to the velocity with which the loop (magnet within flashlight) moves between the two regions. Therefore we can induce that the the difference between each recorded observation emanates from the inconsistency of the person agitating the object (human error). The amount of vigor and energy applied to the object directly affects the speed of the magnet which proportionally influences the sum of voltage recorded. Ultimately, we logically deduced that as our number of shakes increased, so did our sum square voltage.
