Question

lines of force are disturbed. this induces a current in the coil. the image below shows a generator. what could be done to make the lamp less bright? a. use a lamp that lights up with a lower current b. turn the coil faster c. increase the strength of the magnets d. move the magnets farther from the coil

Explanation:

The brightness of the lamp depends on the induced current in the generator. Moving the magnets farther from the coil reduces the magnetic - field strength interacting with the coil, decreasing the induced emf and current, thus making the lamp less bright. Using a lamp that lights up with a lower current would make it brighter if the current remains the same. Turning the coil faster and increasing the magnet strength both increase the induced current, making the lamp brighter.

Answer:

D. move the magnets farther from the coil
