Answer:
Question 1:
Materials:
- Two bar magnets
- A piece of paper
- Iron filings
Procedure:
- Place the two bar magnets on a piece of paper.
- Sprinkle iron filings over the paper.
- Observe the pattern of the iron filings.
Question 2:
Expected Results:
The iron filings will align themselves along the magnetic field lines of the two magnets.
The pattern of the iron filings will be different depending on the orientation of the magnets.

Step-by-step explanation:
Magnetic field lines are invisible lines that represent the direction of the magnetic field. The iron filings are attracted to the magnetic field lines, so they will align themselves along the lines.
The pattern of the iron filings will be different depending on the orientation of the magnets.
For example, if the two magnets are facing each other with their north poles together, the iron filings will form a circular pattern around the magnets. If the two magnets are facing each other with their south poles together, the iron filings will form a spiral pattern around the magnets.
