Q1
What is Lenz's law?
The direction of induced current opposes the change in magnetic flux
The induced current flows in the same direction as the change in magnetic flux
The induced EMF is always positive
The magnetic field is always perpendicular to the current
Show Solution
Copy
Lenz's law states that the direction of induced current is such that it opposes the change in magnetic flux that produced it.

Q
Q: What is Lenz's law?
Solution:
Lenz's law states that the direction of induced current is such that it opposes the change in magnetic flux that produced it.
Steps: 5
Show Steps
Step 1: Understand that Lenz's law is about electricity and magnetism.
Step 2: Know that when a magnetic field changes, it can create an electric current.
Step 3: Realize that Lenz's law tells us how that current behaves.
Step 4: Remember that the induced current will always try to oppose the change in the magnetic field.
Step 5: Conclude that if the magnetic field increases, the induced current will flow in a direction to decrease it, and vice versa.
