Lenz's law Flashcards
1
Q
What is Lenz’s law?
A
An induced current has a direction such that the magnetic field due to the current opposes the
change in the magnetic flux that induces the current.
2
Q
What does Lenz’s Law state?
A
An induced current has a direction such that the magnetic field due to the current opposes the
change in the magnetic flux that induces the current.
3
Q
What are the key points to understand?
A
Emf is present even when it’s not part of a circuit (Faraday’s law)
* Complete circuit → Current → Lenz’s law
4
Q
What is the process of determining the direction?
A
Increase in flux (in/out); Emf is induced; Induced current as per Faraday’s Law; and Direction of current (Lenz’s law)
