The magnetic field due to the induced current in a conductor opposes the change in magnetic flux inducing the current.
Right-hand rule for straight conductors: The thumb points in the direction of the current while fingers curl in the direction of the magnetic field around a conductor.
Right-hand rule for a loop: Fingers curl in the direction of the current. Thumb points in the direction of the magnetic field.
Using Right-hand rule for straight conductors: An increasing magnetic field is directed into the page through the loop.
What is the direction of the induced current in the circular loop due to the current shown in each part of Fig. 21-10?
