Final answer:
The induced current in a conductor is primarily influenced by the speed of movement through a magnetic field and by the resistance of the loop within which it flows; the resistance of the galvanometer affects only the detection of that current.
Step-by-step explanation:
An induced current in a conductor depends on several factors, but the speed with which a conductor moves through a magnetic field plays a significant role. In the context of Michael Faraday's experiments and discoveries, it is the change in magnetic field that causes an emf (electromotive force), which in turn is responsible for inducing a current. For instance, Faraday's law states that the induced emf in a wire moving through a magnetic field is calculated using the formula ε = Blv, where B is the magnetic field strength, l is the length of the wire in the field, and v is the velocity of the wire.
A critical aspect that affects the induced current, besides the change in magnetic flux, is the resistance of the loop through which the current flows. However, the resistance of the galvanometer itself does not directly influence the emf generated; instead, it can impact how well the galvanometer can detect the current flowing through the circuit. In the practical application of these principles, such as in the operation of electric generators, understanding the relationship between motion, magnetic fields, and the resulting electrical effects is essential.
