Hey guys. Quick question on inducing a current. Lets say I have a closed loop of coil and next to it I have a live wire with current going down the wire (think of it from a bird's eye view). So if the current in the wire is increasing, then which direction will the induced current flow, clockwise or anti-clockwise?

I get the easy induced current questions with the left-hand rule for generators but I'm not really sure what's moving in this scenario.
This is a question from the Jacaranda HSC textbook in Ch.7 (if anyone wanted to know :S)

THANKS!!! in advance.

increasing current ---> increasing magnetic field ---> due to lenz's law an induced current in the coil will be generated such that it will oppose the original change in flux, the direction of this induced current will be counter-clockwise if u figure it out.

Yes adding onto stampede's answer

I drew a diagram. The induced current will produce a magnetic field which opposes the original magnetic field generated by the supplied current (Lenz's law)


The green crosses and dots are the flux and the red arrow is the direction of the induced current.

Oh forgot to mention. I knew the direction of the flux by using the Right hand grip rule :)

Thanks again for your help. :)
