Sorry for the un-informative question, but I am new here and am only 13 years of age. What causes magnetism, and why is it that only certail substances can be Magnetized, and others cannot.
Magnetism is a physical phenomenon that is caused by the movement of electrically charged particles. It is the force that attracts or repels objects made of certain materials, such as iron or steel, to a magnet.
Magnetism is caused by the alignment of microscopic magnetic domains within a material. These domains are made up of tiny clusters of atoms that have their own magnetic fields. When these domains align in the same direction, they create a larger magnetic field that can attract or repel other magnetic objects.
Magnetic fields are the invisible areas that surround a magnet. They are created by the movement of electrically charged particles, such as electrons, within the magnet. These fields can exert a force on other magnetic objects, causing them to move or align in a certain direction.
There are three main types of magnetism: ferromagnetism, paramagnetism, and diamagnetism. Ferromagnetism is the strongest and most common type, seen in materials like iron and nickel. Paramagnetism is weaker and is seen in materials like aluminum and platinum. Diamagnetism is the weakest type and is seen in all materials, but is usually only noticeable in materials like copper and gold under certain conditions.
Magnetism has many practical applications in everyday life. It is used in electric motors, generators, and transformers, which are essential components of many electronic devices. Magnets are also used in compasses for navigation, and in MRI machines for medical imaging. Magnetic materials are also used in credit cards, computer hard drives, and speakers.
