**Step-by-Step Solution:** 1. **Understanding the Concept of Induced Current**: When there is a change in the magnetic field around a conductor, an electromotive force (EMF) is induced in the conductor, which causes a current to flow. This phenomenon is a result of electromagnetic induction. 2. **Identifying the Nature of the Change**: The change that induces the current can be an increase or decrease in the magnetic field strength. For example, if a magnet is moved towards a coil, the magnetic field through the coil increases. 3. **Application of Lenz's Law**: According to Lenz's Law, the direction of the induced current will always be such that it opposes the change that produced it. This means if the magnetic field is increasing, the induced current will flow in a direction that creates a magnetic field opposing the increase. ...
