IronNickelCoblatand Alloys
Four common ferromagnetic materials found in nature are iron (Fe), nickel (Ni), cobalt (Co), and their alloys. These materials exhibit strong magnetic properties and are widely used in various applications such as in electromagnets and magnetic storage devices.
The collective term for the four materials you are referring to is not specified in your question. However, if you're referring to common materials like wood, metal, plastic, and glass, they can generally be categorized as "construction materials" or "raw materials." If you have specific materials in mind, please provide their names for a more accurate answer.
Four materials commonly found in soil are sand, silt, clay, and organic matter. Sand provides good drainage, silt is rich in nutrients, clay provides structure, and organic matter helps retain moisture and supports microbial life.
Carbon, Hydrogen, Oxygen and Nitrogen
Iron, Nickel, Cobalt and Gadolinium are the 4 metallic elements with strong magnetic properties but their are more materials than can be magnetic. Steel is an iron alloy that is magnetic. Stainless steel is an alloy of iron, chromium and maybe other materials. Not all stainless steel is magnetic. The amount of magnetic material in it (iron, nickel) determines if it is magnetic or not. ALNICO magnets made of Aluminum, Nickel, and Cobalt are very strong permanent magnets. Ceramic magnets are made of a powdered magnetic material mixed with a ceramic material that gives them a softer texture that will not scratch surfaces and they are popular as refrigerator magnets.
Materials found underground include minerals (such as gold, silver, copper), fossil fuels (such as coal, oil, natural gas), groundwater, and rocks (such as granite, limestone). Other materials like diamonds, gemstones, and ores can also be found underground through mining and excavation.
Four common magnetic materials that are strongly attracted to a magnet are iron, nickel, cobalt, and certain alloys of these metals. This is because these materials have unpaired electrons in their atomic or molecular structure, which creates a magnetic moment. When a magnet is nearby, the magnetic field of the magnet aligns the magnetic moments of these materials, causing them to be strongly attracted to the magnet.
carbohydrates proteins lipids nucleic acids
The four most common elements found in organic formulas are carbon, hydrogen, oxygen, and nitrogen. These elements form the building blocks of organic molecules like carbohydrates, proteins, lipids, and nucleic acids.
The most common state of matter on Earth is liquid. This includes water, which covers most of the planet's surface, and various liquids found in living organisms and everyday materials. Additionally, liquids have the ability to flow and take the shape of their container.
They can usually be found within the same patch.
