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).

How are some flower petals adapted to attract pollinators?
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.
Does two object attract each other?
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.
Why will water form droplets on a smooth surface such as a counter top?
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.
Do magnets repel non magnetic materials?
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!!! ; )
What do electromagnets attract?
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.
What are electromagnets used to record information on?
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.

The movement of Atoms as they attract, move and repel.

Why like charges repel and unlike charges attract each other?
The reason why some charges repel while unlike charges attract comes down to polarity. According to Newton, with every action there is an equal and opposite reaction. The reason comes down the the amount of protons and electrons in each atom. Equal amounts produce a repelling action where as charges with unequal protons and elections will cause the atoms to attract.
What is the hypothesis of magnets?
They have North and South poles, and can attract different things, such as iron, paper clips, other magnets, and some metal. It can also repel other magnets.
Do magnets have more force when they repel or attract?
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)
Why do some magnets bounce back when you try to put them together?
A magnet has two poles, the north and the south. Opposite poles attract, meaning that a north pole will attract a south pole. Same poles repel; a north pole repels another north pole and a south pole repels another south pole. If two magnets attract each other, that pulls them together, and if they repel each other, that pushes them apart. That is the phenomenon that you observed, of magnets bouncing back when you try to put them together.
How does your laundry get static cling?
when various fabrics rub together, excess charges are picked up by some and lost by others, creating a build-up of charges. opposites attract--like charges repel
