SOME Electromagnet like permanent magnets have two poles(north/south). Likewise the rules for SOME Electromagnets are the same as those of a permanent magnet(same poles repel, different poles attract).
No some things repel it like a duck's feathers
Flower petals modify its color, shape, sensitivity, scent, and pattern to attract pollinators. The petal shapes also closely adapt to the pollinator's feeding and landing preferences.
The gravitational force between two objects always acts to attract them together. Electrically charged objects can attract if they have opposite charges, or repel if they have the same type charge. Thus only gravity could have caused matter in the universe to condense together and eventually form stars and planets.
Water does not particularly want to form a dome, or it would be better to say, form a droplet, on a dirty surface. See related questions below. Water forms droplets when the cohesion of water with itself is larger than the adhesion of water to the surface. A dirt surface cold be anything; hydrophobic or hydrophilic, soluble or insoluble, rough or smooth, hot or cold. All these things matter. See links below.
No, a magnet does NOT have the ability to attract materials that are NON-magnetic (unless it has something magnetic on it, or has magnetic material in it). Duhhh!!! I'm in seventh grade and even I know that!!! ; )
Unlike normal magnets, electromagnets attract just someof the alloys that contain iron, such as steel and iron, but not all of them. Electromagnets do not attract aluminium, copper, titanium,brass, bronze, tin, nickel, platinum, gold, silver, lead or pewter.Contrary to some opinions, electromagnets cannot attract cardboard.See also the related question.
Electromagnets...electromagnets are magnets attract, or pull, some kinds of metal objects. Stronger magnets exert a greater pull on the objects they attract. Sometimes it would be useful if you could turn off a magnet when you did not want it to attract objects. That is what an electromagnet can do. Some electromagnets .in power plants and factories electromagnets are very large. You can make a small, simple electromagnet in school or at home.
No, not all force fields can attract and repel. Some force fields, like magnetic fields, can both attract and repel objects with opposite magnetic polarity, while others, like gravitational fields, only attract objects and cannot repel them.
The movement of Atoms as they attract, move and repel.
Some people believe magnetic copper bracelets repel arthritis but it has not been medically proven. The magnets in the bracelets are said to attract and repel charged blood particles.
it could attract and repel some objects and may could mess up some tv's and game system
The repel force is mostly a little stronger than the attraction. I have succeeded of doing this and the answer I found is repel force. (Some stupid people says that they have equal force but they're wrong)
Magnets have invisible forces that attract or repel things. They have two ends called poles - a north pole and a south pole. Opposite poles attract each other, while the same poles repel each other. This is why magnets stick to some things but not others.
Some objects that contain electromagnets are doorbells, speakers, printers, and calculaters
The hypothesis of magnets is that they contain invisible forces that attract or repel certain metals based on their polarity. This hypothesis explains the observed behavior of magnets interacting with each other and with magnetic materials.
Materials such as wood, plastic, glass, and paper do not contain magnetic properties and therefore do not attract or repel magnets. Additionally, non-magnetic metals that are not ferromagnetic, such as copper, aluminum, and brass, do not interact with magnets and are not repelled by them.
Some common types of electromagnets include solenoids, toroids, and horseshoe magnets. These electromagnets are widely used in various applications such as relays, motors, MRI machines, and speakers.
