WARNING!!! This experiment can be dangerous, I recommend anyone to try it without nails

WOW, I discovered this magnetic effect almost by chance by testing for another experiment. it is amazing how fast the arrow is shot from the magnets with hole. To obtain the weapon effect, the arrow and the launcher must have the same polarity. If the polarities are opposite you still get a nice effect like a tractor beam.

The magnetic fields of the dart and of the launcher interact with each other. When the dart is located exactly in the center of the launcher the attractive and repulsive forces are in balance and contains a high potential energy (the same amount of energy that I used to let the dart into the launcher). when I push the dart the system exits from equilibrium and the repulsive force prevails over the attraction, and the dart is fired.

for arrow i use this magnet

for the pitcher choose a magnet with hole greater then 4mm
i use 30x3mm and hole 5mm anf 15x5mm and 5mm hole

On my channel you will find all the ways to have fun with magnets divided into 3 main categories:

Classical magnetic experiments such as magnetic levitation, homopolar motors, small magnetic weapons, Gauss cannons, gears, magnetic field viewers and much more.

Satisfaction video like the construction of magnetic sculptures, slime and magnetic putty and product review.

ASMR relaxing videos to watch but above all to listen preferably with stereo headphones to be able to appreciate the particular sounds of the magnets

All ways to have fun with magnets.

The magnetism has always intrigued me. The strength of the magnets is scientifically explainable but there's something "magical" about its interaction with the world. My Channel offers you curious experiments and fun games to do with magnets.
