Aim: to test the Faraday relationship: induced e.m.f. equals the rate of change of magnetic flux linkage(adsbygoogle = window.adsbygoogle || []).push({});

flux linkage = NBA

N=number of turns in coil

B=magnetic flux density

A=area of the coil

To investigate the relationship above first i must have two quantities constant while the thired is varied.

from what i understand i should keep t constant and vary the rest and plot e.m.f vs N

then keep N constant and vary the rest and plot e.m.f vs I both of these graphs i think should give a staight line.

apparatus used would be: pair of solenoids of square cross-section; one has twice the area of the other

signal generator: use the low impedance output and set the frequency on the 100 Hz to 1000Hz range.

Cathode ray oscilloscope for measuring the peak induced voltage.

magnetic flux linkage = NBA

e.m.f= NA dB/dt

but dB/dt is porportinal to I and I is proportional to f

therefore e.m.f = NAf

i'm lost up to this point if i do all of this, what can i conclude anout the Faraday relationship.what other readings must i take etc.. please help
