The resistance of the loop is 0.55 Ω. At what rate the magnetic field strength increasing or decreasing? (a=8.4 cm, I=148 mA. Give answer in T/s.)
The loop is a square, so all the distances around are a=8.4 cm
dI=rate of change of the flux
The Attempt at a Solution
I found V by using Ohm's Law V=IR, which is the same as emf
but now I am lost, I feel like I need to find B, obvious reasons. Do I just use the equation
N=1 because only 1 loop
R=radius, so half of a?
