Electro-magnetism
No, not all materials have magnetic properties. Materials like iron, nickel, and cobalt are examples of ferromagnetic materials, which exhibit strong magnetic properties. However, materials like wood, plastic, and glass are not magnetic.
No, wood is not magnetic because it does not contain any magnetic properties within its natural composition. Magnetic materials are usually metallic, such as iron, nickel, or cobalt.

ferro magnetic substances can be magnetised. but it is not necessary that all the Ferro magnetic substances can be permanently magnetised. it depends on the alignment of domains in the substance.for example wrought iron can be magnetised permanently but soft iron can only be magnetised temporarily(Electro Magnets).
A freely moving magnet will align itself in a north-south direction, pointing towards the Earth's magnetic poles. This behavior is due to the magnet's natural attraction to the Earth's magnetic field lines.
The three substances that form natural magnets are iron, nickel, and cobalt. These elements have magnetic properties due to the alignment of their atomic structure, which allows them to attract other materials and create a magnetic field.
No, calcium is not magnetic. It does not have magnetic properties in its natural state.
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.
This may shock you, but all matter is magnetic just to varying degrees. So yes there is. Here are the 4 levels of magnetic property's if you will. and examples of the minerals that have them.Ferromagnetism - a strong attraction to magnetic fields. examples would be Magnetite and Pyrrhotite.Paramagnetism - a weak attraction to magnetic fields. Example would be Platinum,Diamagnetism. , Bismuth Is the only mineral that is diamagnetic, meaning it is repelled from magnetic fields.Magnetism. Only a variety of one mineral acts as a magnet, generating magnetic fields on its own. This mineral is Lodestone, the magnetic variety of Magnetite, which found in only a few deposits throughout the world. Although it is only weakly magnetic, its magnetism is definitely discernible.
An attraction or force between particles that causes them to combine.

Natural magnets, such as lodestone, cannot be easily controlled in the same way artificial magnets can be. However, their magnetic properties can be influenced by external factors like temperature and pressure. Additionally, they can be used in conjunction with other materials and magnetic fields to create devices that harness or direct their magnetic forces, such as in compasses or magnetic sensors. For precise control, electromagnets are typically preferred, as their magnetic strength and polarity can be adjusted by changing the electrical current.
