Question

The relation between the charge flow \(\Delta Q\) through the circuit of resistance \(r\) and the change in the magnetic flux \(\Delta \phi_B\) is

• A. \(\Delta Q=\dfrac{\Delta \phi_B}{r}\)
• B. \(\Delta \phi_B=\dfrac{\Delta Q}{r}\)
• C. \(\Delta \phi_B=\Delta Q\)
• D. \(\Delta \phi_B=-\dfrac{r\Delta Q}{q}\)
• E. \(\Delta Q=-\dfrac{\Delta \phi_B}{r}\)

Hint:

For total induced charge: \[ Q=\frac{\Delta \phi}{R} \] This is a standard one-step result from Faraday's law and Ohm's law.
