Final answer:

The current in the secondary coil of a transformer is induced by the magnetic field of the primary coil and can result in different voltages depending on the number of windings in the coils. The induction of current in the secondary coil occurs in the opposite direction to that of the primary coil.

Explanation:

The current in the secondary coil of a transformer is induced by the magnetic field of the primary coil. This is due to Faraday's Law of electromagnetic induction, where a changing magnetic field in the primary coil induces a current in the secondary coil.

This current in the secondary coil can lead to different voltages depending on the number of windings in the coils, determining if the transformer is a step-up or step-down transformer.

Additionally, the current in the primary coil creates a magnetic field transmitted to the secondary coil, causing the induction of a current in the secondary coil in the opposite direction to that of the primary coil.
