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.

What is the real test for magnetism?
The real test for magnetism is to see if a material can attract other materials like iron or steel. This can be done by bringing a magnet close to the material and observing if there is an attraction or repulsion. Alternatively, one can use a compass to see if the material can influence its direction.
Is earth's north magnetic pole aligned with its north goegraphic pole?
It is an unusual question, but yes, the North and South poles do contribute to Earth's gravity. They are like giant magnets pulling things to Earth. I hope this answers your question. If not ask a real scientist.
Are zen magnets or nanodots better?
nano dots by far The first reason that Nanodots are superior to zen magnets is that they have a higher quality product. Nanodots are engineered to a precise size and shape, which allows you to build large and complex structures. They actually built the Guinness World Reccord Magnetic Sculpture. The World Record weighs over 320 kg and contains over 550,000 magnets. Nanodots will last forever because of their good quality. And unlike zen magnets, Nanodots come in 4 colours, 2 of which are coated in real silver and real gold! Also, if you check out www.thenanodots.com - they offer you tutorials on how to build lots of cool creations using Nanodots. They offer better support to customers and people who love the product. Nanodots are also offering accessories such as the Nanopad! The Nanopad is a perfect accessory for Nanodots as it provides the ideal surface for building with Nanodots and playing Nanodots games on. And the Nanopad features a dot counter to help build with Nanodots quickly and easily. Enjoy Nanodots Read more: Why are nano dots better than zen magnets
How magnet detect real gold?
Magnets are not able to detect real gold. This is because gold is not magnetic; it does not have any magnetic properties. If a magnet is attracted to an item that appears to be gold, it likely contains other metals that are magnetic.
Why are nano dots better than zen magnets?
Nano dots are better than Zen magnets because they are typically more uniform in size and shape, leading to better performance and consistency in applications like data storage or biomedicine. Additionally, nano dots can have enhanced magnetic properties due to their small size, making them more suitable for certain specialized uses.
Why do some objects not attract to magnets?
they aren't made out of real metal.
Does real gold and silver stick to magnets?
No, real gold and silver are not magnetic materials, so they do not stick to magnets. Magnets only attract materials that contain iron, nickel, or cobalt.
How do electromagnets find uses in a vending machine?
Electromagnets are used in vending machines to deciever real coins from fake ones. Electromagnets will sort counterfeit money from real money, because most counterfeit money is an iron alloy. Iron is magnetic and gets pulled by the electromagnet, while real coins are not effected.
What will happen if a child swallows small magnets?
I think that the child will die because of the chemical that is in the magnet,if it swallows a magnet.Ans. 2Almost all really small magnets are ferrite, or other similar ceramics. These are not water soluble, and therefore won't poison anyone. The only real danger is if the child swallows lots of small magnets; magnets attract each other and could form a clump large enough to cause an internal blockage.
How electromagnets are used in real world?
Every electric motor and generator uses an electromagnet.
What was magnets real names in the book Holes by Louis Sachar?

How are electromagnets used in the real world?
Electromagnets are used in various real-world applications such as MRI machines in medicine, maglev trains for transportation, and in industrial settings for lifting and separating metal objects. They are also used in speakers, electric motors, and generators.
Can magnets be made?
The metal must be able to conduct an electromagnetic charge.The most common types of metal that can conduct the charge are, Iron, Cobalt, and Nickel.Now there are places in the world that naturally have good sources of electromagnetic energy. However there are plenty of machines that provide the same benefit.Have you ever wondered why you can put magnets onto your refrigerator? Even if your refrigerator is mostly made of plastic and/or foam, it somehow produces enough energy to attract a magnet. The iron coils in the back emit electromagnetic energy, that distributes around the entire fridge, allowing magnets to stick on like magic.Magnets have two poles, positive energy, and negative energy. Or (going back to science class) Electrons and Protons of atoms. When a piece of iron is exposed to a high percentage of electromagnetic energy the electrons and protons will become charged.In order to craft a magnet, a piece of iron, cobalt or nickel could simply be hit by a bolt of lightning, or shocked from a generator.However be very careful when creating a magnet. If it is done in a hazardous fashion the magnet could create explosions or malfunctioning of electrical equipment. Magnets can destroy computers, and even devastate telephone transformers. Magnets can also screw with radio signals or compasses and make them malfunction.If you are curious as to where you can find magnets in everyday life here are a few things engineers and scientists use magnets for today:The Superman extreme roller coaster uses magnets to pull the train to give it a strong enough acceleration boost to complete the track.A famous monorail in Japan was the first to use magnets as a clean source of energy to get it smoothly through the city. The magnets are used much like The Superman roller coaster. The magnets are placed on the track and underneath the monorail cars, the forces of the magnets allow the train to literally defy gravity.Another awesome fact about magnets is that our very planet has its own electromagnetic pole. It is the North Pole. Compasses are designed to always point north because the magnet inside was made to pick up electromagnetic charges in the area to show direction.
Does the compass have to have a magnet to work?
Yes, a compass relies on a magnetized needle that aligns with the Earth's magnetic field to indicate direction. If the magnetism is lost, the compass will not function properly.
What are some examples of some real life electromagnets?
Some examples of real life electromagnets include: MRI machines used in hospitals for medical imaging, loudspeakers in audio systems, and magnetic door locks.
Can a real gold necklace stick to magnets?
No, gold is not magnetic and will not stick to magnets. If a gold necklace is sticking to a magnet, it may be a different metal alloy or a fake gold piece.
Is there a Magnet to check if something is real gold?
No, magnets cannot accurately determine if something is real gold. Gold is not magnetic, so a magnet will not stick to or react to real gold. It's best to consult with a professional jeweler or use other testing methods like acid testing to determine the authenticity of gold.
