The north pole of a magnet is brought near a coil. The induced current...
The direction of the current will be anticlockwise.
 
According to Lenz's law, the current in the coil will be induced in the direction that'll oppose the external magnetic field .
As the flux due to the external magnet is increasing ( as the N-pole is brought close ) , the coil will have to induce current in the anticlockwise direction to oppose this increase in flux and not in clockwise direction as that'll end up supporting the external flux.

It's simple as the magnet is brought near the field lines going inside the coil increases and so to oppose the change the current will generate in anti lock direction to oppose the field lines. So option B is the correct answer

The north pole of a magnet is brought near a coil. The induced current...
The direction of the induced current in a coil can be determined using Faraday's law of electromagnetic induction. According to this law, the induced current in a coil is always in such a direction that it opposes the change in magnetic field that is causing it. Based on this principle, we can determine the direction of the induced current when the north pole of a magnet is brought near a coil.

First, let's consider the initial situation when the north pole of the magnet is far away from the coil. In this case, there is no change in the magnetic field and therefore no induced current in the coil.

When the north pole of the magnet is brought closer to the coil, the magnetic field near the coil increases. This increase in the magnetic field induces an opposite magnetic field in the coil, according to Lenz's law. The induced magnetic field in the coil opposes the north pole of the magnet.

Next, let's consider the right-hand rule to determine the direction of the induced current. If we point our thumb in the direction of the magnetic field induced by the north pole of the magnet, and curl our fingers around the coil, the direction of the induced current will be opposite to the direction in which our fingers curl. This is known as the right-hand rule for the direction of the induced current.

In this case, when the north pole of the magnet is brought near the coil, the induced current will flow in the anticlockwise direction as seen by an observer on the side of the magnet. This is because the anticlockwise current creates a magnetic field that opposes the north pole of the magnet, satisfying Lenz's law.

Therefore, the correct answer is option 'B' - the induced current in the coil will be in the anticlockwise direction.
