Question 1.
What does Lenz's Law state?
Show hintHide hint
Think about the relationship between current and magnetic flux.
Question 2.
If a magnet is moved away from a coil, what happens to the induced current's direction?
Show hintHide hint
Consider how the current needs to respond to changes.
3Question 3.
What is the direction of the induced current according to Lenz's Law?
