Why does this image represent a metal that is magnetized?

• This doesn't represent a metal that is magnetized.

• All metals are magnetized.

• Because all of the magnetic domains are flowing in the same direction.

• Because all of the magnetic domains are flowing in opposite directions.

Which of these explains why the woman will be shocked when she touches the doorknob?

• She won't get shocked because the doorknob doesn't let electricity flow through it.

• She won't get shocked because static electricity doesn't exist.

• When she touches the doorknob, the buildup of electrons will flow out of her because the doorknob is a conductor that allows electrons to flow freely through it.

• When she touches the doorknob, the buildup of electrons will flow out of her because the doorknob is an insulator  that allows electrons to flow freely through it.
