38 why are some magnets stronger than others

Curious Kids: How and why do magnets stick together? The energy needed to pull magnets apart comes from you, and you get it from the food you eat. And the plants or animals you eat get their energy from other plants and animals, or from the Sun. All ... What is Magnetism? - The Wonders of Physics - UW-Madison Magnets seem to act something like positive and negative electric charges. Electricity and magnetism are very closely related. If the words north and south remind you of anything, the earth is in fact a giant magnet. A compass is a tiny magnet balanced on a point so it can turn freely. The magnet is attracted by the earth's magnetic north ...

What makes some magnets stronger than others? - reddit A magnet is strongest if all the tiny magnets formed by the crystals in it all line up with each other in the same way. When this happens, the little magnets all add together to make a strong big magnet. If any of the little magnets inside don't line up right, then their strength is taken away from the total, and the magnet is weaker.

Why are some magnets stronger than others

Why are some magnets stronger than others? | Questions | Naked Scientists They get all jiggled up and end up pointing in random directions again. With very strong magnets, like rare earth magnets, the structure of the alloy tends to make it very hard to change the direction of the magnetic field. This means that more of them stay lines up, and you get a stronger magnet. Strongest and Weakest Parts of a Magnet - ThoughtCo The magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole when compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center. If you were to sprinkle iron filings on a piece of paper and place the magnet beneath it, you could ... How to Make Magnets Stronger? - Stanford Magnets Steps to Make a Weak Magnet Strong Again. Firstly, you need to put the weak magnet within the magnetic field of a much larger, stronger magnet . To achieve the best result, you need to place it right next to the larger, stronger magnet, which will help realign electrons in the weaker magnet that have spun out of axis.

Why are some magnets stronger than others. Why is the Earth's magnetic field stronger than its neighbors? Potassium-40 has not been ruled out because the neutrinos from 40 K decay are too low in energy to detect, but that brings us back to problem #1. The only hope for this conjecture is that potassium somehow becomes siderophilic at high pressure. There are some experimental results, most of which are highly controversial, that this might be the case. Magnetism for Kids | First4Magnets They are made by heating up magnetic material such as iron to really high temperatures and then cooling it in the presence of a really strong magnetic field. This makes some of tiny the particles, known as magnetic domains, within the magnet face the same way. Why Do Magnets Repel Each Other? - Reference.com This magnetic field is the result of the movement of negatively charged electrons within the magnet. These fields are strongest directly at the pole, which is why the ends of magnets will so powerfully repel or attract each other. Magnets are constructed from one of the magnetic metals, such as iron, nickel or cobalt. Which shape of magnets is the strongest? - Magnetpartner.com The shape of the diameter can cause a bigger pole, which means, that you can make your magnets stronger, by giving them a bigger pole. So, depending on how big you make your cylinder or disc magnet, you can make them very powerful by creating a bigger surface. Just as they have done to the world's biggest magnet.

Why are some magnets stronger than others - Science Mathematics With very strong magnets, like rare earth magnets, the structure of the alloy tends to make it very hard to change the direction of the magnetic field. This means that more of them stay lines up, and you get a stronger magnet. - Well, you first need to know how magnets work in the first place. How to Compare the Strength of Magnets: Lesson for Kids - Study.com If you put two magnets near each other, the north and south poles will attract, or pull towards each other, but the two north poles or two south poles will repel, or push away from each other. If... What Determines the Strength of a Magnet | US Magnetix These substances have high magnetic permeability and make the strongest magnets. Iron, cobalt and nickel are among these substances. Neodymium iron boron (NdFeb) makes the most powerful magnets. Neodymium magnets are so powerful, in fact, that a NEO magnet weighing only a few grams can still attract up to 1,000 times its own weight. Learn What Metals Are Magnetic and Why - ThoughtCo Magnets are materials that produce magnetic fields, which attract specific metals. Every magnet has a north and a south pole. Opposite poles attract, while like poles repel. While most magnets are made from metals and metal alloys, scientists have devised ways to create magnets from composite materials, such as magnetic polymers.

Magnet Experiment: Are Two Magnets Twice as Strong as One? Why? Two magnets together will be slightly less than twice as strong as one magnet. When magnets are stuck entirely together (the south pole of one magnet is connected to the north pole of the other magnet) you can add the magnetic fields together. What Makes Magnets Strong? | Sciencing This is the first of the factors that determines how strong a magnet becomes. The second is the type of material the magnet is made of. Different materials produce magnets of different strengths. Those with a high magnetic permeability (which is a measurement of how responsive they are to magnetic fields) make the strongest magnets. Strongest Magnets - first4magnets Neodymium magnets are so strong because of their high resistance to demagnetisation (coercivity) and their high levels of magnetic saturation allowing them to generate large magnetic fields. A magnet's strength is represented by its maximum energy product value (BHmax) which is measured in Mega Gauss Oersteds (MGOe). Is a bigger magnet stronger than a smaller magnet? - Answers Yes a bigger magnet wil be stronger that a smaller m agnet becasue ut has more mass than that of a smaller one, therefor more electrons and more attraction. This is not always true, some super ...

Why are some materials magnetic? - BBC Science Focus Magazine It's the result of the motion of electrons inside atoms. When electrons move through a wire, the resulting current generates a magnetic field. Electrons inside atoms are also moving: they orbit the central nucleus of atoms, and spin on their axes. In most atoms, the resulting magnetic effect is weak.

Why are certain metals more magnetic than others? What is a ... - Quora Magnetism appears as a backward "family bond" between the substance AETHER, which fills the infinite universe, from which the matter is formed, and the "liquid state" of matter-free gluons. These materials have a stronger magnetic feature, if they have more proton neutrons in them.

The human magnetic field. Do some people have more magnetic properties ... For a magnetic field to be strong enough to damage a watch, it has to be much stronger than the Earth's field… which means that it would be easily detected with a compass. If your watches tend to stop, there could be many explanations. But if a compass goes crazy when you wave your wrist near it, THAT would be interesting!

Why are some magnets stronger than others? - Quora But, yes, we can make a magnet stronger than corresponding natural one of the same size. This is because we can artificially force the orientation of maximum atomic magnets in one particular direction. Naturally this can occur in small sizes but rarely can happen in larger sizes.

Why certain things are easier to magnetize than others? EgadsNo. Uhm yes and no, keeping in mass is already "full" of electricity, but not potential difference you must remember that electrons are moving through materials- infact the more heat the more they (free electrons) are moving around and producing magnetic fields. As explained in a recent article on physorg the electrons in magnets have ...

How Magnets Work | HowStuffWorks In magnets, on the other hand, most or all of the magnetic domains point in the same direction. Rather than canceling one another out, the microscopic magnetic fields combine to create one large magnetic field. The more domains point in the same direction, the stronger the overall field.
