2. Clip the iron clip on the magnet and put it on the table.

3. Put the paper cup, stick and clip with magnet together and prepare for combination.

4. Hang the clip on the stick and put it in the middle of the paper cup.

5. Tie the small screw with iron wire and wrap it with a small stick to prepare for the magnetic levitation test.

6. Lift the clip with your left hand, put it down, put the small screw hung with wire near the paper cup, pick up the stone suction clip with your left hand, lift it down, and pick up the stick tied with the small screw with your right hand, and put the small screw hung with wire near the paper cup.

7. By observing and exploring the principle of magnetic levitation, the effect of magnetic levitation in small batch production is finally verified.
