Magnetism Help

Err, your thumb points in the direction of positive current, and your fingers curl in the direction of the magnetic field.

 

Whatever change in magnetic flux there is, the induced current will make a magnetic field to counter that change in flux.

 

Curl your fingers around a wire and point your thumb in the direction of current. Then curl your fingers around the wire in a way that you're opposing the change in flux. Your thumb will be in the direction of the induced current.
