Faraday’s Law
Objective:
To become familiar with the concepts of changing magnetic flux and induced currents associated
with Faraday’s law of induction.
● Part I (EMF 2Hz)
○ Firstly, we assembled the experimental setup for Faraday's law of induction.
■ Helmoltz coils, small coil, voltage sensor, and the magnetic sensor were
set up accordingly.
■ R (avg radius) = 0.10715m
Helmholtz coil
■ N_t (number of turns) = 500
Helmholtz coil
■ A (cross-sectional area) = 7.306*10^-4 m^2
Small (induced) coil
■ N (number of turns) = 2000
Small (induced) coil
○ The set up was linked to the computer software to ultimately display three graphs
■ V = Voltage (V) Graph
■ I = Current (A) Graph
■ B = Magnetic field strength (T) Graph
● Part II: (EMF 4Hz)
○ Same process the only difference is the Frequency; in which has been increased
from 2Hz to 4Hz.
● And from both results; info was recorded:
Conclusion:
We ultimately changed magnetic flux and induced currents associated with Faraday’s law
of induction; illustrated results graphically through capstone, and changed frequency and its
effects.
