Feel Flux turns a falling metal ball into a slow-motion lesson in Lenz's law. Here's how the magnetic slider toy works and what to expect before you buy.
Quick answer
Feel Flux is a handheld science toy: drop the metal ball through the suede-wrapped copper tube and it sinks in slow motion, demonstrating Lenz's law. It is a demonstration piece, not a building set, so it suits curious kids and adults who enjoy a visible physics effect.
Why the ball slows down
The ball contains a magnet, and the copper tube is a conductor. As the magnet passes through, it generates an electrical current in the copper, and that current creates a magnetic field that opposes the ball's motion. The result is a gentle braking force you can watch in real time, which is why the ball appears to fall in slow motion rather than dropping straight through.
What the suede wrap does
The suede wrapping on the copper tube is a handling detail: it gives you a comfortable grip and protects the tube surface. It does not change the physics. Expect the tube to feel warm or smooth in the hand, and treat it as a precision object rather than a rough-and-tumble toy.
Who it suits and who it doesn't
This is a good fit for a child who asks how things work, or for an adult who wants a desk object with a genuine scientific principle behind it. It is less suitable for very young children, who may lose the small ball or drop the tube, and for anyone expecting a programmable or buildable kit. The appeal is the effect itself, repeated and observed.
Feel Flux FAQ
- What is Feel Flux?
- A handheld device consisting of a suede-wrapped copper tube and a metal ball with a magnet inside. Dropping the ball through the tube produces a slow, resisted fall.
- How does Feel Flux work?
- The moving magnet induces a current in the copper, and that current creates an opposing magnetic field. This is Lenz's law in action, and it is what makes the ball seem to float downward.
- Is it a magnetic slider toy?
- Yes, in the sense that the ball slides through the tube under magnetic braking. It is not a slider puzzle or a track set; the play is dropping the ball and watching the effect.
- Is it a good science toy for kids?
- It works well as a demonstration for school-age children who can handle the ball carefully and understand a simple cause-and-effect explanation. For toddlers, the small ball is a choking hazard and the tube may be dropped. Check the child's age and handling habits before buying.
- What should I expect in the box?
- Based on the catalog, the set centers on the copper tube and the metal ball. No additional accessories are listed, so plan on using it as a standalone demonstration.
Product facts
- Feel Flux: The metal ball falls through a suede-wrapped copper tube, creating a slow-motion sensation. This is the core experience, so set expectations around observation rather than assembly.
Feel Flux - Feel Flux: The effect relies on Lenz's law, generated by a magnet inside the ball interacting with current in the copper tube. Knowing the principle helps you explain the toy to kids and connect it to real physics.
