In Faraday’s experiment if the magnet is moved towards the coil,...

Explanation:

When a magnet is moved towards a coil, it results in a change in the magnetic field at any point on the wire loop. This change in magnetic field induces an electromotive force (emf) in the coil. Let's discuss why option 'C' is the correct answer.

1. Faraday's Experiment:
Faraday's experiment is a classic experiment that demonstrates the phenomenon of electromagnetic induction. In this experiment, a coil of wire is connected to a galvanometer or an ammeter. When a magnet is moved towards the coil, the magnetic field passing through the coil changes, which induces an emf in the coil.

2. Magnetic Field Change:
When the magnet is moved towards the coil, the magnetic field passing through the coil increases. This is because the magnetic field lines are being concentrated and passing through a smaller area (the coil). So, the magnetic field at any point on the wire loop increases.

3. Deflection of Galvanometer:
A galvanometer is a device used to detect and measure small electric currents. In Faraday's experiment, when the magnetic field at any point on the wire loop increases, it induces an emf in the coil. This emf causes a current to flow through the galvanometer, resulting in a deflection of the galvanometer needle. The direction of the deflection depends on the direction of the induced current.

4. Conclusion:
Based on the above explanation, we can conclude that when a magnet is moved towards the coil in Faraday's experiment, it results in an increase in the magnetic field (option 'C') at any point on the wire loop. This increase in magnetic field induces an emf in the coil, causing a deflection in the galvanometer.

Therefore, option 'C' is the correct answer.

Read the following text and answer the following questions on the basis of the same: Galvanometer can sense/measure current. Improved mirror galvanometer was developed by William Thomson, later to become Lord Kelvin, in 1858. Thomson intended the instrument to read weak signal currents on very long submarine telegraph cables. The fundamental problems of transmitting/ receiving a signal through a lengthy submarine cable was that the electrical current tended to be very low (as little as 1/100,000th of a standard light bul b). So, it was very difficult to detect it. To solve the problem it was thought that larger amount of electric current would be sent through the line. But Thomson had a different approach. He thought the best response was to devise a device that could read faint signals. The galvanometer, first invented in 1802, was a means of detecting electric current. It consisted of a needle that was deflected by the magnetic field created by the electric current. But the galvanometers of the day couldn't detect the weak signals that came through a long underwater cable. But the improved version of galvanometer was highly sensitive to detect the lowest current. The mirror galvanometer consists of a long fine coil of silk-covered copper wire. In the heart of that coil, within a little air-chamber, a small round mirror is hung by a single fibre of floss silk, with four tiny magnets cemented to its back. A beam of light is thrown from a lamp upon the mirror, and reflected by it upon a white screen or scale a few feet distant, where it forms a bright spot of light; when there is no current on the instrument, the spot of light remains stationary at the zero position on the screen; but the instant a current traverses the long wire of the coil, the suspended magnets twist themselves horizontally out of their former position, the mirror is inclined with them, and the beam of light is deflected along the screen to one side or the other, according to the nature of the current. If a positive electric current gives a deflection to the right of zero, a negative current will give a deflection to the left of zero, and vice versa.
