2. Clip the iron clip on the magnet and put it on the table. Next, clamp the iron clip on the magnet and put it on the table, as shown in the figure below.
3. Put the paper cup, stick and clip with magnet together and prepare for combination. Then, put the paper cup, stick and clip with magnet together to prepare the combination, as shown below.
4. Hang the clip on the stick and put it in the middle of the paper cup. Next, hang the clip on the stick and put it in the middle of the paper cup, as shown in the figure below.
5. Tie the small screw with iron wire and wrap it with a small stick for magnetic levitation test. Then tie the small screw with iron wire and wrap it on a small stick to prepare for the magnetic levitation test, as shown below.
6. Lift the clip with your left hand, put it down, and put the small screw hanging with wire near the paper cup. Then pick up the stone-absorbing clip with your left hand, lift it up and put it down, and pick up the stick with the small screw tied to it with your right hand, and put the small screw with the wire hanging on it near the paper cup, as shown below.
7. Check the effect of magnetic levitation in small batch production, and finally verify the effect of magnetic levitation in small batch production by observing and exploring the principle of magnetic levitation. Through observation, we can see the small screw swinging around the paper cup, just like dancing. When the magnet swings on a stick, the magnetic field will change constantly, which will cause the magnetic force on the small screw to change and make the small screw swing constantly.
