A tube made of copper and a small neodymium ball… is all you need to eliminate gravity and to make magneto-dynamics a meditative exercise, in a fascinating way. Simply let the ball slide into the tube and feel the magic that happens inside. But wait! Neodymium? Magneto-what?
Because of the neodymium, the shiny ball is not just any ball; it's an exceptionally strong magnet. Letting it fall into the tube will result in a changing magnetic field. According to Faraday's law of induction, this will create an electromotive force. This will induce so-called eddy currents, which will create another magnetic field. This is where Lenz's law comes into effect: it states that the magnetic field generated by the currents is always directed in the opposite direction of what caused them –- the falling neodymium ball in this case. It thus floats through the copper tube veeery very slowly.
What makes Feel Flux so special.
Whether it's used for relaxation purposes or to help those who like to have something to keep their hands busy, or whether it's used as a unique way to practise ones skills by those who want to be like the "Master of Magnetism" himself; Magneto... once you've got your hands on Feel Flux, you'll never want to stop dropping the ball into the tube. Yes, it's that addictive!
And Feel Flux isn't just further proof that physics is exciting. Because of its high-quality materials, the neodymium ball, the copper tube and the fine leather belt that covers it means it also looks great and feels good!
With great power comes great responsibility
Even though the ultra-magnetic ball is great for exciting experiments, you should also be aware that such a strong magnet can cause harm to certain devices like hard drives, mobile phones, and medical equipment, and so it should be kept away from these kinds of things as well as other magnetic objects. 30cm or so is a safe distance.
