Right-hand rule for straight conductors: Thumb points in the direction of current, fingers curl in the direction of magnetic field.

Right-hand rule for lops: Thumb points in direction of the magnetic field. Fingers curl in the direction of the current.

Lenz's law:

The induced current creates an induced magnetic field that opposes the change in magnetic flux inducing it.

(a)

The field due to the wire carrying a current in loop A is into the page. The change in flux is increasing.

The induced field is out of the page to oppose the increasing flux.
