Carefully review the general safety advice on the back of the box cover before starting the experiment.
Read the "Magnets and electricity" section of the safety guidelines carefully before proceeding. Do not let children under 8 years old handle small magnets.
Disassemble the setup after the experiment.
Dispose of solid waste together with household garbage.
You’ve seen that the magnets repel each other when their like poles are facing one another. How will the magnets behave if their like poles are above each other?
Two magnets placed sideways or above each other feel both of their neighbor’s poles. If the magnets are close enough, they’ll turn to let the attractive force win, unless they are braced to restrict turning.
In this experiment, the magnets are fixed and positioned one above the other so that like poles are closer than opposite poles. Therefore, they repel each other, suspending the rod in midair without visible support. If you look at the installation from above, you can see that the rod is hovering in the middle between the base magnets , since it is repulsed equally from both sides. If you gently nudge the rod to either side, the repulsion from that side increases and pushes the rod back to its original position (equilibrium).
Curiously, the rod can also rotate as long as the distance between the magnets on it and the base does not change.

Kids are now able to engage with science in a way that they simply wouldn’t have been able to in the past as they shrink themselves down to see the world at a molecular level
