 ===== Induced Voltage and the Electric Field =====
-We know from Faraday's Law that a changing magnetic field will create a curly electric field. If we put a loop of wire nearby, we can add up the little bits of length along that loop with the curly electric field, which tells us how curly that electric field is. (This is very similar to what we did with [[184_notes:loop|Ampere's Law]].) The units of this integral ($\int \vec{E}_{nc} \bullet d\vec{l}$) will give us the same units of electric potential (volts) - $\frac{V}{m}\cdot m= V$. However, because we have curly electric field from the changing magnetic field, this is not technically an electric potential. (When we defined the electric potential __//we made an assumption that all the charges were stationary or not moving,//__ __//**which is no longer the case.)**//__
