last couple i promise!!!

(1)If magnetic field lines are drawn for this bar magnet, which statement would be true?

(2)Why are electromagnets used in metal scrap yards?

(3)The image shows an electromagnet made with a 1.5-volt battery.

How would the magnetic field be affected if you replaced its 1.5-volt battery with a 9-volt battery while using the same nail and coil?

(4)What does this diagram represent?

other question and images for questions are below!

Number 1:  Field lines loop around the magnet starting at the north pole and ending at the south pole.

Number 2: They are temporary magnets that can be turned on and off.

Number 3: The magnetic field strength would increase.

Number 4: The diagram represents the electrical input charging the machine, giving a rotating loop mechanical output.

Number 5: The colored wires because wires have electrical resistance.
