Here are seventeen of our own best magnetic techniques, projects and demos.
Extract battery packs from stubborn holders We’ve all got points that take battery packs. Many are developed, and a few of these aren’t. The worst offenders include digital toys that just take (proclaim) half dozen AA batteries, which needs to be inserted together with the correct direction– springtime area very first– and pried
See studs in your structure
Push a magnet over the wall surface until they locates a screw or nail-head in paint. Your don’t also have to draw the wall– you can just leave the magnet here and soon you’ve drilled the openings.
Make a homopolar engine
One of the favored demonstrations of them all are a homopolar motor. a magnetic, a wire, a power supply and a screw are you’ll want to make a motor twist to 10,000 rpm.
Generate LED Throwies directed throwies are of help for many more things than graffiti. We’ve generated variants from backyard bulbs to origami to handmade cards, but it’s perhaps not a genuine throwie without a magnet.
Demonstrate magnetohydrodynamic propulsion
You could make your personal caterpillar drive such as the one in The look for Red October because of this magnetohydrodynamic demo.
Fool around with the coolest doll actually ever: 512 1/8? cube magnets Available from K&J Magnetics, this really is enough magnets to truly have some fun. Most magnet root come in the links point.
Create straightforward compass
We’ve formerly found how to make stupidly easy compasses that drift on water or spin on a sleek surface. Here’s another process: sandwich a thread between two quite strong magnets and hang they straight down for an instantaneous compass.
Try out self installation In an activity that is nearly the same as installation of biological molecules or amazingly development, arbitrarily purchased magnets can around automagically means by themselves into cool chains. Below are a few magnetized self installation video clips.
Generate almost everything (ferromagnetic) into a building set
With magnets as connections, you are able to establish tins into what you including. (be sure that you see Bawls Mints, perhaps not Bawls hype).
Generate a Curie motor A Curie engine makes use of temperature to demagnetize an area of a magnetic, triggering it to move out of the temperature where in actuality the period initiate once more. On BoingBoingTV, Mark Frauenfelder helps guide you to construct one with a candle, a wire and a couple of magnets.
Freaking awesome processor films
Fold during the open-top with the bag and set magnets on each side to put on it sealed.
Fool around with eddy current damping Drop a magnetic down an aluminum or copper pipe, and you’ll discover a hanging sluggish trip triggered by eddy current damping. Here’s a fast videos.
Render a fridge pencil
Slide a tiny magnet beneath the material clip on a pen (these uniballs include our favorite) and you will keep a pen helpful throughout the refrigerator for your shopping list and phone information.

When you actually wish to accomplish one thing ridiculously dangerous like laser engrave your fingernails, you’ll requirement magnets to disable the magnetized interlocks.
Generate any such thing into a fridge magnet We like which will make unusual points into refrigerator magnets. Which secret has actually sometimes fooled people into attempting to open all of our refrigerator magnets to take into account chocolate.
Demonstrate diamagnetic levitation By placing diamagnetic material (like bismuth or graphite) between big magnetic and limited one, possible levitate the small one. Outlined instructions and hyperlinks to kits with this are on costs Beaty’s webpages, amasci.com.
Awake their notebook or put it to sleep lots of notebooks bring a magnetized switch that tells the pc to attend sleeping whenever the top closes. Earlier Macs could possibly be deceived into turning in to bed making use of their covers right up by waving a magnet by the higher right hand area of the cover.
