HITASION Moondrop Fidget Desk Toy Displaying Gravity On The MOON (Rose Gold) - Product Description
HOW IS IT WORK?
We would love to tell you that we have discovered the ''anti-gravity formula'' but actually it is simple physics. The surprising movements of Moondrop are caused by Lenz's law which is well known in physics world.
Moondrop is made from pure copper or aluminium ring, aluminium body and strong neodium magnets inside the thin aluminium tube.
Copper and aluminium is a non magnetic materials however they are great conductors of electricity while each magnet is surrounded by it's own magnetic field. When the magnet moves through conductor such as sliding copper ring it's magnetic field induces an electric current in the copper.
According to Lenz's law that current creates an opposite magnetic field that adds certain resistance to moving magnet. That makes the slider move slower than it would normally do if made from other materials (without electrical conductivity). Depending on proportions between magnet and conductor different sliding speed can be achieved.
The slider is made from pure copper. The distance of falling slider is 38 mm. The time for slider to fall that distance is 0,13 s which is the same as for any object dropped on the Mars and falling it's first 38 mm.
Turn any of Moondrops into Earth version by removing the magnets and compare the gravity between all three.
Gravity falling objects also have acceleration therefore it is measured with m/s- that means the longer they fall the faster their falling speed is. Using Lenz's law we can not achieve that acceleration however the distance is so small that the acceleration is almost invisible with naked eye and the free-fall looks as natural as it would look on Moon and Mars.
HITASION Moondrop Fidget Desk Toy Displaying Gravity On The MOON (Rose Gold) - Details
- 1.WHAT IS IT?-Designed with science in mind and crafted using amazing laws of physics Moon drop seemingly defies gravity and let's you explore the free fall on the Mars and Moon.
- 2.WHO NEEDS?-Whether you are a fidgeter, science enthusiast or just love cool gadjets you will enjoy playing around with it.It is a very satisfying fidgeting toy as .You can flip it, slide it, spin it and fidget any way you like.
- 3.WHAT IS MADE?-Moondrop is made with the latest cutting edge technology using precision CNC machining to ensure the perfect quality to every unit. The body is crafted from Aerospace grade Aluminium which is very durable and light weight. The slider is made from same aluminium or pure copper depending on edition you choose. Each aluminium part is anodized for surface protection.
- 4.HOW IT WORKS?-The gravity on the Moon is 1,6 m/s² which is only about 1/6th of that on Earth. Since there is vacuum on the moon there is also no air resistance- this makes any object no matter how big free fall in the same speed.
- 5.WHERE PLAY?-Each Moondrop comes with beautiful desktop stand. It is pocket sized and perfectly fits in a palm so you can take it anywhere you go.Such as work,meeting,home,relaxing.
