club knob - magnetic flux

$10.00

Vision clubs with magnetic knobs and caps? Yes please! Magnetic flux caps and knobs enable you to explore new manipulation techniques and blow minds. 

Flowtoys magnetic club knobs are very strong and designed for maximum flux (magnetic force), with a compromise in weight. Please read description below for details and limits of our warranty on the magnets.

Sold individually. Comes with 1 knob w/ inset magnet and screw.

NOTE: As of 2/14, magnetic knobs will be 3D-printed rather than foam. We are making them and will start shipping after 20 February. Even if you order Express shipping, they may not ship until after 2/20.

WARNING: Please ONLY use the screw that comes with the flowtoys club knob (or check the Tech Specs for the screw we use) - other screws may be too long and may drill through the circuit board and damage the top LED. Please note that we cannot warranty your board in full if this happens.

  • Description

    Flowtoys magnetic club knobs are designed for maximum flux (magnetic force) and contain 2 x 1” x 1/8” countersunk   Neodymium magnets. The polarity is reversible and you can remove one magnet to reduce the weight and strength:

    • magnetic knobs weigh 32g (with screw), while standard knobs weigh 6g (with screw)
    • we include 2 magnets for maximum flux, but we also include a spacer that can replace one of the magnets to reduce the weight by 10g, and make it weaker if desired.
    • magnets are brittle and can chip or shatter on impact with hard surfaces. 
    • avoid juggling over hard surfaces like concrete, stone or tile.

    A word on warranty:

    We cannot warranty the magnet as there are no appropriate shatterproof magnets. If you break a magnet, you can order more from the club parts category (soon), or from your preferred magnet source. 

    The knob's magnets are a N42 Strong Neodymium Magnet with the following dimensions and polarity:

    • 2 x 1" diameter x 0.125" thick with 0.355" x 0.195" 82 degree taper countersunk hole (#8 countersink)
    • countersunk on opposite poles (reversible as a pair)

    There are many potential combinations of polarity possible, but most of them would require keeping track of which club is which. To make them universal, we have chosen South pole for the caps (not reversible) and recommend North for knobs, so all caps attract all knobs, but repel each other, so you can not connect cap to cap, but the knobs DO attract each other quite well on the sides and you can even hang 3 clubs by their knobs from the knob of a fourth!

    Warning about replacing club knobs:

    In order to maximize the amount of light near the knob, the screw is very short and can easily be stripped out. Please be careful to use great force when screwing the knob in (you read that right - use force). You should be pushing it in hard, while screwing so it does not act like a drill. Be sure to screw it in deeply/firmly, so it does not easily rip out during use. 

    Minimize how often you replace the screw/knob. It is not intended to be swapped out frequently. While we have had success with 20+ replacements, it will eventually wear out the hole and the club will need to be sent in for servicing.

    Please ONLY use the screw that comes with the flowtoys club knob - other screws may be too long and may drill through the circuit board and damage the top LED. Please note that we cannot warranty your board in full if this happens.
