Magnetism is the class of physical attributes that occur through a magnetic field, which allows objects to attract or repel each other. Because both electric currents and magnetic moments of elementary particles give rise to a magnetic field, magnetism is one of two aspects of electromagnetism.

6 天之前 · Magnetism, phenomenon associated with magnetic fields, which arise from the motion of electric charges. It can be an electric current in a conductor or charged particles moving through space, or it can be the motion of an electron in an atomic orbital. Learn more about magnetism in this article.

2019年11月5日 · Magnetism is defined as an attractive and repulsive phenomenon produced by a moving electric charge. The affected region around a moving charge consists of both an electric field and a magnetic field. The most familiar example of magnetism is a bar magnet, which is attracted to a magnetic field and can attract or repel other magnets.

2022年2月2日 · Magnetism is a force of nature produced by moving electric charges. Sometimes these motions are microscopic and inside of a material known as magnets.

2023年10月19日 · Magnetism is the force exerted by magnets when they attract or repel each other. Magnetism is caused by the motion of electric charges. Every substance is made up of tiny units called atoms. Each atom has electrons, particles that carry electric charges. Spinning like tops, the electrons circle the nucleus, or core, of an atom.

2024年4月9日 · Magnetism is a phenomenon induced by the force exerted by magnets, which produces fields that attract or repel other metallic objects. It occurs as a result of electrically charged particles.

Magnets and Magnetic Fields: A brief introduction to magnetism for introductory physics students.

2022年8月30日 · Magnetism is one aspect of the the fundamental electromagnetic force. It describes phenomena and forces associated with magnets or magnetic objects. All magnetic fields are generated by moving charge or changing electric fields.

What Is Magnetism? At its core, magnetism is a physical phenomenon by which materials exert attractive or repulsive forces on one another. This effect is primarily observed in materials like iron, nickel, cobalt, and certain alloys, known as magnetic materials.

Magnets are made from magnetic metals such as iron, nickel, and cobalt. Magnets come in all shapes and sizes – you might have seen some of these in your school: Magnetism works over distance so...
