Introduction: Magneeto Floating Wheels (from ScienceKitShop.com)

The new and improved version of the Floating Wheels using Magnet Strips is very close to 100% magnet levitation! The idea is making a wheel and axle that will float above a pair of strip magnets and can rotate with no friction.

Step 1: Kit Contents

Here is what is included in the kit. The only other material you will need is a string and some wood glue.

Step 2:

Start off by inserting the eye screw into the 1 1/2" Bass Wood.

Step 3:

Glue the 1 1/2" Bass Wood on one end of the 7" x 1/2" x 1/2" Bass Wood.

Step 4:


Center and Glue the 3 1/2" x 1/2" x 1/2" Bass Wood on the opposite end.

Once that dries, glue the flat wood strips on the sides with the bottom ends lined up evenly with the table as pictured.

Step 5:


Once the glue dries, remove the backing on the adhesive side of your magnet strip and place it on the wood with the sides laying on the wood strips as pictured.

Step 6:

Insert an eye screw into one end of the wood dowel and then place the magnet rings on the ends. It's important that the polar sides should be facing the same way on both magnets.

Attach your thread or string to the two eye screws. Make sure you have sufficient string so that you can adjust it later on so the magnet rings levitate over the strips.

Step 7:

Here is where it gets a little tricky and we will need to do some adjusting and positioning.

Using one hand, grab the other magnet strip and put it under the inner magnet ring to see if the dowel levitates. If you see that you have no luck whatsoever, you will have to change the side of one or both of the magnet rings so they repel against the magnet strip.

Step 8:

Once you have success in finding the right polar sides so that that dowel with magnet rings repel and levitate, make a light mark with a pencil so that you can position and glue your other 3 1/2" x 1/2" x 1/2" Bass Wood.

Then repeat the same steps for attaching the flat wood strips and magnet strip.

Step 9:

Repeat the same steps for attaching the flat wood strips and magnet strip onto the Bass Wood.

Step 10:

Adjust the length of your strong so that the rings "float" over the magnet strips.

Step 11:

You may prefer to cut the magnet strips and wood pieces to give your finished kit a "cleaner" look. Use this example to get an idea of what it will look like.

How are the ring magnets polarized? How are the magnetic strips polarized?

The magnet strips have only one pole but the ring magnets have a S & N on each respective side so you will have to see which side repels and adjust accordingly : )

Clarification - I don't think there is such a thing as a single magnetic pole. They always exist in N-S pairs. You mean that since the magnetic strips come with adhesive on one side, there is only one possible orientation, correct?

You are correct. Thanks for making it more clear. Since the adhesive side will be facing the wood in this particular model, we're only dealing with one side and therefore will only have to adjust the ring magnets to repel against that side. Interestingly, some magnets (especially fridge magnets) have both N&S on the same side.

Yep - this page has some nice illustrations of different ways magnets can be polarized:

How much force can you put on it? imagine modding this to be a frictionless bicycle hub!

author
ScienceKitShop (author)JM19992014-10-04

In this particular model, not much force. The friction-less bicycle is an interesting idea though.

Cool idea! Looks like this could be done pretty easily with off-the-shelf items. Thanks for sharing this.

Thanks and glad you enjoyed it. You're right but to save time and money, we've put the essential materials together. All you'll need is string and wood glue.
