ok, ive posted the ans asked by me....the others shud also do it, i guess.

Remember Cedric. Remember, if the time should come when you have to make a choice between what is right and what is easy, remember what happened to a boy who was good, and kind, and brave, because he strayed across the path of Lord Voldemort. Remember Cedric Diggory.

1. bcoz of eddy currents
2. its bcoz an atom on the whole is electrically neutral.
