ok, not exactly a techie, but I do know my stuff. in short, they do repel. every magnet has to sides, a south and a north, like sides repel,oppositesattract, blablabla, you learned all of this a long time ago. well, a neocube's magnets are no different: each magnet has a south and a north, just like any other self respecting magnet. when put together in a cube (or any other shape, for that matter) all of the spheres have their south poles on one side, and the north poles on the other. the cube itself will form one large magnet as it were, having both a south pole and a north pole, dictated by theorientationof the mini spheres. this also means that if you were to take two assembled neocubes and bring their like sides near each other, they would repel. if you brought theiroppositesides close, then they would yank together and smash into a giant crumpled mess.
Electromagnets are just as "real" as permanent magnets and behave in exactly the same way (as long as there's current flowing through them). So, yes: the north pole of a permanent magnet will attract the south pole, and repel the north pole, of an electromagnet.
Oh, dude, totally! Magnets can totally attract metal in water because water doesn't really affect the magnetic force. It's like the metal in water is all, "Hey, magnet, I'm coming your way!" and the magnet's all, "Cool, come on over, metal buddy!" So, yeah, magnets can totally pull metal out of water like it's no big deal.
Magnets have long been claimed to have biological effects though no careful objective clinical trials have ever demonstrated this. Nonetheless, there is a thriving business associated with "healing magnets." The magnets sold as healing magnets are made from the same materials as all other magnets are made from. Examples of the magnets and their use include the following. a) FLEXIBLE MAGNETIC RUBBER Flexible magnetic rubber magnets are commonly formed in sheets or strips and used for magnetic therapy in shoe insoles.. b) CERAMIC MAGNETS Ceramic magnets are most commonly used in body wraps, pads and cushions. c) NEODYMIUM MAGNETS Most commonly used in magnetic jewelry, bracelets, and individually on pain trigger or acupuncture points. d) SAMARIUM COBALT MAGNETS Most commonly used magnets in high quality jewelry where rusting is to be avoided. A very expensive magnet, very brittle, therefore labor intensive. e) HEMATITE MAGNETS Beaded magnetic hematite is very commonly used as bead magnets in high quality jewelry where bead strands are used to create beaded hematite bracelets, beaded hematite necklaces, or beaded hematite belts. With hematite the jewelry is the magnet rather than a magnetic insert into the jewelry.

I make small ufo's in copper, I just finished one , using 2 neo. magnets repelling each other, causeing one edge of the ship to hover upward, while the other end is hinged, will they repel for years or not. I don't want it coming back in the future.

not always as the south pole of a magnet is magnetic yet it repels another south pole. :D
A perpetual magnet wheel generates continuous motion without an external power source through the interaction of magnetic fields. The magnets on the wheel repel and attract each other, causing the wheel to spin continuously. This motion is sustained as long as the magnets maintain their magnetic properties.
The electrostatic force between the spheres causes them to repel each other. This force creates a tension in the threads, which can be broken down into vertical and horizontal components. By setting the vertical component equal to the gravitational force, you can solve for the angle theta.
You can cause the leaves of an electroscope to repel each other by introducing a charged object near the top of the electroscope, which will induce a charge separation in the leaves. If the leaves are made of a conductive material, the like charges in the leaves will repel each other, causing them to diverge and stay that way as long as the charged object is present.
Long dry hair tends to create static electricity when brushed, causing the hair strands to repel each other. This repulsion occurs due to the friction between the hair and the brush, resulting in the strands moving away from each other. Conditioning the hair or using an anti-static spray can help reduce this effect.
Permanent magnets.
Permanent magnets are made from materials that retain their magnetic properties for a long time without the need for an external magnetic field. Examples include neodymium magnets and samarium-cobalt magnets. These materials have high coercivity, which allows them to maintain their magnetism over long periods.
Yes, you can add magnets to your refrigerator door as long as it is made of a magnetic material like steel. Magnets can be a fun way to display notes, photos, and other lightweight items on your refrigerator. Just be mindful not to use magnets that are too heavy or strong, as they may damage the door or the items attached to it.
