Hi,
This is not a formal HW question, yet I was wondering whether one of you might be willing to answer it nevertheless.
According to Fraday's law, ε = -∂[itex]\phi[/itex]/∂t. If I reversed the direction of the current in an inductor used to measure ε, would that have any effect on ε?
I would think it wouldn't, but am not certain. Wouldn't the flux remain the same once the current is reversed? Or, rather, the rate of change of flux?
