 · Why is Iron Magnetic? Announcing a discovery of the shape of the nucleus of Iron. Magnetism is caused by the protons in Iron making a shape. Iron has a nucleus with two loops of protons coaxial with isolated protons. See the article in The Journal of Nuclear Physics, March, 2019. "Magnetism from iron''s nuclear structure".

 · A iron bar near a magnet willbe attracted to the magnet regardless of the directionthe iron bar faces. Or, why will an iron bar be attracted to either end of a magnet, but a magnet will not be attracted to either end.thanks - rdh (age 7-) gv, ca, usa. A: The iron bar is filled with magnetic domains. Each is like a little magnet, but usually ...

Ferromagnetism is the basic mechanism by which certain materials (such as iron) form permanent magnets, or are attracted to magnets physics, several different types of magnetism are distinguished. Ferromagnetism (along with the similar effect ferrimagnetism) is the strongest type and is responsible for the common phenomenon of magnetism in magnets encountered in everyday life.

 · Why is Iron Magnetic? The magnetic property of iron largely depends on its electronic configuration, [Ar] 3d6 4s2, with 4 unpaired electrons. Parallel alignment of the 4 unpaired electrons is another important reason for its magnetism. And in addition to that, the crystal structure of Iron also plays a role in its magnetic property.

Why don''t magnets stick to aluminum? - The Straight Dope

Magnetic fields exert forces on current-carrying wires. In this lesson, learn how magnetic fields are created and calculate the force a magnetic field will exert on a current-carrying wire.

 · The amount of iron in an adult''s body put together is 3.5g. The iron contained in blood only is just 2g. This small amount is spread all over the body, so obviously, it isn''t greatly affected by the pull of magnets. But this explanation isn''t perfect. Because in the case of super magnets, it could attract any magnetic substance no matter ...

 · Types of Rust and its Magnetic Nature Red Rust. The red rust is caused due to presence of high oxygen or water exposure to the iron. This forms the hydrates ion Fe 2 O 3.H 2 0 and the hydrate ions of iron are magnetic. Thus, the red rust is magnetic.

 · Different types of iron and steel are more or less magnetic. High-chromium stainless steel is nearly non-magnetic, while pure iron tends to form magnets easily. Iron with impurities usually stays magnetic better than pure iron, however. As for "non-ferrous" materials, it''s pretty hard to make any generalizations.

 · A magnetic field is generated by what''s called a dynamo, which is caused by the fluid motion of a conducting material, such as liquid iron. In the case of the Earth''s magnetic field, this motion occurs in the planet''s outer core, and is caused by the convection of heat. But the moon isn''t large enough for convection to take place.

The magnetic property of a material is due to the alignment of its dipole or magnetic moment. Iron atom has an unpaired electron that can be lined...

 · Iron and other ferromagnetic materials (that is, ones that are naturally drawn to a magnet) are themselves made up of lots of tiny magnets. Put a chunk of iron next to a permanent magnet and these tiny magnets all line up in parallel. This allows the iron to produce its own magnetic field and attract the permanent magnet. For this to happen, a ...

Why will dropping an iron magnet on a concrete sidewalk make it a weaker magnet? Vibrations provide energy to randomize the magnetic directions of the domains. The source of a magnetic …

Why is iron magnetic? The long-sought explanation of the origin of ferromagnetism, which involves interactions both among the bound electrons and between bound and itinerant electrons, will guide the search for new magnetic alloys. Mary Beth Stearns The unravelling of the origin of magne-tism in iron, cobalt, nickel and their alloys

 · Iron is a kind of metal. Metals can also be magnetic. Iron is magnetic, too. That''s why you can grind up some cereals and get the iron out with a magnet. There might even be some iron in the metal spoon you use to eat your cereal in the morning. If you like food and science, perhaps you might want to be a food scientist one day, Phillip.

Rubbing a magnet along some iron will pull enough atoms into alignment that the iron can stay magnetized itself. Fun Fact: The most powerful magnets are made by melting a special iron alloy, then holding it in an incredibly strong magnetic field while molten until it cools back down to a solid.

 · The grey cast iron is magnetic and exhibits the properties of ferromagnetism. All kinds of grey cast iron especially the graphite structure of grey cast iron exhibit all properties of magnetism that include permeability, coercive force, and hysteresis. Thus, grey cast iron is magnetic.

 · They almost completely cancel each other out. However, sometimes (in iron, nickel, and cobalt for example) you''ll have one or more un-paired electrons. The magnetic fields of these electrons aren''t canceled out by another, oppositely-oriented, electron. As such they lend an overall magnetic field to the atom they inhabit.

Why is iron attracted to a magnet, but chromium isn''t? Physics. (Below 38 degrees Celsius, at least.) The explanation I''ve always gotten is, roughly, ''well, in chromium each atom pairs with another atom, cancelling out the magnetic field'' (i.e. antiferromagnetism) - but this leaves a lot to be desired. Why do such pairings form in chromium but ...

In order for an atom to be magnetic it have to have and unpaired electrons because in a filled shell all the electrons are paired so the electrons cancel out each other. As far as we know, electrons have a stronger magnetic field than a proton so ...

 · What makes iron, cobalt and nickel magnetic? Electrons have spin, a property that gives them a magnetic moment it creates a magnetic field. The spins of electrons in most atoms are paired up and so their magnetic effects are in effect cancelled …

Why is iron magnetic? The long‐sought explanation of the origin of ferromagnetism, which involves interactions both among the bound electrons and between bound and itinerant electrons, will guide the search for new magnetic alloys. Mary Beth Stearns. Ford Motor Company, Dearborn, Michigan. PDF.

 · Magnets attract iron due to the influence of their magnetic field upon the iron. Before a piece of iron enters the magnetic field of a magnet, the polarization of the iron s atoms is random.

 · Why Is Iron Magnetic and Wood Not? Each atom of iron has an unpaired electron whose spin can be lined up to that of the unpaired electron from a neighboring iron atom. The spinning of the charged electron creates a magnetic moment, which in turn can align with an external magnet, thus making iron magnetic. Atoms of wood do not have unpaired ...

 · Iron is magnetic except when heated to the Curie point. The Curie point, which is sometimes called the Curie Temperature, is the temperature at which some magnetic materials undergo a major change in their structure. The Curie point for iron …

 · To greatly simplify, iron is attracted to magnets because the atoms in a solid chunk of iron have a stable magnetic spin. This means when a magnetic field is applied, the magnetic poles of all the ...

Most metals with magnetic properties are ferrous: metals and alloys that contain iron. These ferrous metals include mild steel, carbon steel, stainless steel, cast iron, and wrought iron. Their high carbon content leads to being prone to rust (with the exception of stainless steel and wrought iron), but their tensile strength and durability ...

Valuable features of iron oxide nanoparticles in bioapplications include a tight control over their size distribution, magnetic properties of these particles, and the ability to carry particular biomolecules to specific targets. The internalization and half-life of the particles within the body depend upon the method of …

 · Iron is magnetic. So, any metal with iron will be attracted to a magnet. Some metals like copper, gold and aluminium are non-magnetic. Not all iron is magnetic. Iron is a ferromagnetic which is attracted to the magnets like nickel and cobalt. It is non-magnetic because they have net dipole moment of zero and have partially field electron shell.

 · Stuart - The fact that blood contains iron is one of the reasons why some people believe magnetic bracelets might have an effect on the human body. However, blood is not magnetic in a conventional sense. In other words, it is not ferromagnetic which is what most people understand as magnetism. If blood was ferromagnetic, then people would bleed ...
