Will real magnets attract or repel electromagnets?
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.
Why don't neocube magnets repel?
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.
How did David Levy and Gene Shoemaker meet each other?
they met each other a long time ago
What are types of healing magnets?
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.
Where magnets originated?
Magnetic therapy dates as far back as the ancient Egyptians. Magnets have long been believed to have healing powers associated with muscle pain and stiffness. Chinese healers as early as 200 b.c. were said to use magnetic.
I use them in art work how long before repelling magnets break down and no longer repel each other?
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.
There are two 5.0 g spheres each suspended from 1.0 m long threads The spheres repel each other after being charged to 91nC What is the angle theta?
There are two 5.0 g spheres each suspended from 1.0 m long threads The spheres repel each other after being charged to 91nC. The angle theta is 0.0265 radians.

What magnets are made from materials which retain their magnetic properties for a long time?
Permanent magnets.
What kind magnets are made from materials which retain their magnetic properties for a long time?
Permanent magnets.
How do you know magnets were used a long time ago?
we know because magnets were first found in 1200
How are protons and electrons linked?
Protons and electrons are linked numerically; in any atom the number of protons and electrons is the same eg in carbon there are six of each. They have equal and opposite electric charges in an atom. The negative charge of each electron exactly balances the positive charge of each proton.
How long does it take for magnets to rust?
5 months
Permanent magnets and electromagnets both hold their magnetism for a long period?
the answer is false Permanent magnets will hold their magnetism for a long period of time. Electromagnets will only remain magnetic as long as current is flowing through them.
How did sea captains use magnets long ago?
As compasses.
How are temporary and permanent alike?
they're both magnets . they can both stick to iron-made materials. They are different because temporary magnets only last a little and permanent magnets last a long time.
