Lenz's Law states that the direction of the induced electromotive force (emf) and hence the induced current in a closed circuit is always such that it opposes the change in magnetic flux producing it. This law is a manifestation of the conservation of energy.

Here are the steps to understand it:

1. When a magnetic field within a closed loop of wire changes, an electromotive force (emf) is induced in the wire. This is a result of Faraday's law of electromagnetic induction.

2. According to Lenz's law, the induced emf will generate a current that creates a magnetic field opposing the initial changing magnetic field.

3. For example, if the magnetic field through the loop increases, the induced current will flow in such a direction that it will create a magnetic field opposing the increase. Conversely, if the magnetic field through the loop decreases, the induced current will flow in a direction that creates a magnetic field opposing the decrease.

4. This law is a direct consequence of the law of conservation of energy. The induced current will always work to oppose the change in the magnetic field, as allowing it to change unopposed would create or destroy energy, which is not possible according to the law of conservation of energy.
