Lenz's Law
Easyphysics
Lenz's law gives direction of induced current such that it?
Select the correct option:
Solution
Incorrect! Answer:
Opposes flux change
- Lenz's Law Statement: The direction of an induced current is such that it creates a magnetic field that opposes the change in magnetic flux that produced it.
- Formula: ϵ=−dtdΦ (The negative sign represents Lenz's Law).
- Physical Basis: This law is a consequence of the Law of Conservation of Energy. If it enhanced the change, energy would be created from nothing, leading to an infinite current loop.
- Application: Moving a magnet toward a coil induces a current that creates a repelling magnetic pole.
