Safety first

Get to know your Feel Flux

Feel Flux gets even more exciting if you know what

happens under the hood. It has nothing to do with

the well known attracting or repelling magnetic

force—the underlying principles are based on an

effect called Lenz's law. Here is what happens

when you drop the ball in the tube.

The movement of the falling ball creates a

changing magnetic field inside the metal wall of

the tube.

According to Faraday’s law of induction, the

changing magnetic field induces a voltage

inside the wall of the tube called electromotive

force.

Because the tube is made of well conducting

metals, this voltage creates eletric currents that

flow round-and-round. These are called

eddy-currents.

According to the law of excitation, the flowing

eddy-currents generate a second magnetic field

that can affect the magnetic field of the ball.

Lenz’s law states that this additional magnetic

field is always directed to oppose the motion

that has generated it: the movement of the ball.

The faster the motion, the stronger the slowing

force gets. When the ball stands still you feel no

attraction at all. This dynamic behavior makes

Feel Flux so satisfying to play with.
