Study Notes
Physics
Physics is the natural science that studies matter, its motion and behavior through space and time, and the related entities of energy and force. It comprises two main approaches, the experimental study of physical phenomena through observation and measurement, commonly referred to as empiricism, and the theoretical development of laws of physics to explain these phenomena, which includes abstract concepts such as forces, fields, and interactions with matter. This combination of observational and theoretical science is called the scientific method.
Electromagnetic Induction
Electromagnetic induction is the process of producing an electromotive force (EMF) in a conductor by moving a magnet through the conductor or moving the conductor through a magnetic field. This process is the underlying principle of electric generators and transformers.
Magnesium Properties
Magnesium is a chemical element with the symbol Mg and atomic number 12. It is a light, silvery-white, alkaline earth metal, and is the eighth most abundant element in the Earth's crust.
Magnetic Fields
A magnetic field is a vector field that describes the magnetic forces experienced by moving electric charges, magnetic materials, and other materials. Magnetic fields are generated by electric currents and by the motion of electric charges, such as electrons, and have sources and sinks where the field lines originate or terminate.
Electromagnetism
Electromagnetism is a branch of physics that studies the interactions between electrically charged particles, such as electrons and ions, and the fields they create. It is one of the four fundamental forces of nature and is the basis for the study of electromagnetic radiation, which includes light and radio waves.
Electricity
Electricity is the flow of electric charge. Electrostatics is the study of electric charges at rest, while electrodynamics is the study of electric charges in motion. Electricity is used in a wide range of applications, from powering devices such as computers and phones to providing light through light bulbs and creating sound in speakers. It is essential for modern society and technology.
