(7) | 01/11/2022 | Translate: A timer that works with magnets and iron filings.
Visualization of magnetic field This is a container which contains iron filings in a viscous clear liquid. By placing a magnet in the center of, we can see that the magnetic field formed.- The magnet game A board game in which two players place small magnetic balls on a special board, trying not to magnetize and stick together. In this case the player collects the balls that have been magnetized. The winner is the one who will remain first without balls in his hands.
- Legos playing drums Building a Lego Technic machine that activates some piezoelectric magnets, and plays drums with a music production software.
- The reaction of copper against strong magnets Ben from the NightHawkInLight channel, experiments with Lenz's law and Faraday's law of induction to create electricity and magnetic fields in copper. Copper is not magnetic, but creates resistance in the presence of a strong magnetic field, causing powerful magnets to slow down when they approach him.
- Free beer if you stop the timer at exactly 10 seconds A young man tries his luck at a fun game in a bar. If he manages to stop the timer at exactly 10 seconds, then he wins a beer.

- Large neodymium magnet against small magnets By James from the channel The Action Lab, trying to bring together a very large and powerful neodymium magnet with 1000 small neodymium magnets. As explained at the end, The power of these magnets is so great that if instead of small neodymium spheres using a piece of metal, It would have definitely suffered major injuries in his hand. This is because the balls beam is not homogeneous and many have their poles in random directions, neutralizing part of the magnetic attraction.
- Citrine: a beautiful crystal The crystal Citrine is a variety of quartz, whose color ranges from light yellow to brown, said iron-containing.
