Magnetic Effects due to Electric Currents Result:
... • ΔФ is change in flux • More rapidly flux changes, the larger the induced voltage (i.e. larger meter swing). • As magnetic flux passes through each loop in coil the total flux, Ф = N .B .A • Thus the more turns of wire, the larger the induced voltage. Example: Determine induced voltage in a coil o ...
