Lenz's Law

How do you know by looking at the picture that magnetic flux has increased?

• Magnetic field has increased in the picture

• Surface area has increased in the pictures

What does a change in FLUX induce?

• Electric current

• Magnetic field

 Why this particular situation would not work?

• Because increase in magnetic flux, increases the current and hence will violate Law of conservation of energy.

•   Because increase in magnetic flux decreases the flow of current and hence violate the Law of conservation of energy

Why would the magnetic field DECREASE the flux? (Hint - RHR)

• Because the induced magnetic field is against the magnetic flux

• Because the induced magnetic field is in the same direction as of magnetic flux

Lenz's Law states that the induced current produces a magnetic field that opposes the magnetic field that caused the induced current

• true

• false
