The S poles of magnetic needles 1 and 2 point to the N pole of the magnet;

The N poles of magnetic needles 6 and 7 point to the S pole of the magnet.

2. How do the magnetic needles ③, ④ and ⑤ point?

The N pole of magnetic needle 3 points to the S pole of magnetic needle 4;

The N pole of magnetic needle 4 points to the S pole of magnetic needle 5.

3. How do the magnetic needles ⑧, ⑨, and ⑩ point?

The N pole of magnetic needle 10 points to the S pole of magnetic needle 9;

The N pole of magnetic needle 9 points to the S pole of magnetic needle 8.

We know that a small needle rubbed by a magnet can point in the direction. Please guess: Does a magnet have this ability? Ask your classmates to try to verify it again.

Verification method 1. Place a piece of foam in a basin filled with water, and then place a magnet on the foam. After the magnet is stable, observe the direction of the magnet and record it.

The N pole points to the south and the S pole points to the north.

Verification method 2: Tie the middle of a magnet with a rope, and then pull the magnet by hand to rotate it. After the magnet stops, observe the direction of the magnet and record it.

The N pole points to the south and the S pole points to the north.

Verification method 3. Place the center of a magnet on a rotating stand, and then pull the magnet by hand to rotate it. After the magnet stops, observe the direction of the magnet and record it.

The N pole points to the south and the S pole points to the north.
