Question 1.
What does Lenz's Law state about induced currents?
Show hintHide hint
Think about the direction of current.
Question 2.
If the magnetic field increases, what happens to the direction of induced current?
Show hintHide hint
Consider the cause and effect.
3Question 3.
According to Lenz’s Law, what happens to the direction of the induced current?
- It helps in increasing the flux
- It opposes the change in flux
- It doesn’t affect the flux
Show hintHide hint
Focus on the word 'opposes'.
4Question 4.
True or False: Lenz's Law ensures that energy is neither created nor destroyed.
- True
- False
Show hintHide hint
Think about energy conservation principles.
Question 5.
Consider a coil of wire connected to a circuit while a magnet is pushed towards it. Describe the behavior of the induced current and its direction when the magnetic field inside the coil increases.
Show hintHide hint
Think about which way the induced current needs to flow to counteract the incoming field.
Question 6.
If a coil experiences a decreasing magnetic field, what direction will the induced current flow, and why?
Show hintHide hint
Consider how the induced current compensates for the change.
