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.
