What does “Lenz's law” actually mean in Magnetism & Electromagnetic Induction, and why does it matter for JEE?
the induced current always opposes the change that produced it, ensuring energy conservation.
In simple words: the induced current always opposes the change that produced it, ensuring energy conservation. Getting Lenz's law clear matters because JEE questions on Magnetism & Electromagnetic Induction usually test this idea directly, not just a formula you memorised.
Key point
Lenz's law
Common mistake
getting the direction of induced current backwards.
Memory tip
nature resists change: the induced current fights the flux change.
