Final answer:
According to Lenz's Law and the right-hand rule, the induced current in a wire loop caused by an approaching north pole of a magnet, when viewed from the left, circulates in a counterclockwise direction.
Step-by-step explanation:
To determine the direction of the induced current in a wire loop when a magnet is moving towards it, we can apply Lenz's Law and the right-hand rule (RHR-2). As the north pole of a magnet approaches a wire loop, the magnetic flux through the loop increases with the lines directed from the front to the back of the loop. According to Lenz's Law, the induced current will flow in such a way as to oppose the increase in flux, which means that the induced magnetic field must be directed from the back to the front of the loop to counteract the approaching magnet's field.
Using RHR-2, if you place your thumb pointing against the magnetic field lines from the magnet, your fingers wrapping around in the direction of the induced current will indicate a counterclockwise direction when viewed from the position of the approaching magnet. Therefore, when the north pole of a magnet is moved towards a copper loop from the left, and you observe from the left, the induced current circulates in a counterclockwise direction.
