Magnetism - Wikipedia
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 .
Magnet - Wikipedia
A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets.
List of Magnetic Metals - Science Notes and Projects
2021年3月2日 · Familiar examples of magnetic metals include iron, nickel, cobalt, and steel. But, magnetism is a complex phenomenon. Not all iron or steel is magnetic. There are even some nonmetals that display magnetism! Here is a review of the types of magnetism, a list of magnetic materials, and a look at metals that aren’t magnetic.
How Magnets Work - HowStuffWorks
2022年9月20日 · Magnets are objects that produce magnetic fields and attract metals like iron, nickel and cobalt. The magnetic field's lines of force exit the magnet from its north pole and enter its south pole. Permanent or hard magnets create their own magnetic field all the time.
Things That Are Magnetic
2023年2月11日 · This article provides a comprehensive list of 50+ things that are magnetic, which includes a variety of everyday objects and advanced technology. Iron - Iron is a naturally occurring metal that is highly magnetic. Iron is a key component in steel and is widely used in various industries and applications due to its strong magnetic properties.
24. Magnetism – Conceptual Physics
Magnetism describes the properties of magnetic objects, which are capable of attracting and repelling other magnets. From using a magnet to post artwork and photos on a refrigerator, to navigating with a compass, to the protection that the Earth’s magnetic field provides for us, magnetism plays a large role in our lives.
Magnetism - 10+ Examples, Types, Properties, Functions
2024年8月28日 · Magnetism is a physical phenomenon where moving electric charges produce magnetic fields that cause attractive and repulsive forces between objects. It is fundamental to various applications, including compasses, electric motors, and data storage devices.
Magnetism: Definition, Types, Properties & How They Work …
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. This is why the phenomena of electricity and magnetism are referred to collectively as electromagnetism.
7.2: Magnets, Electromagnets and Magnetic Matter
2024年2月22日 · Magnetic atoms have both a north pole and a south pole, as do many types of subatomic particles, such as electrons, protons, and neutrons. We know that like magnetic poles repel and unlike poles attract. See if you can show this for two refrigerator magnets. Will the magnets stick if you turn them over? Why do they stick to the door anyway?
A Quick Guide to Magnets, Magnetic Metals & Non-Magnetic …
2021年9月8日 · Magnetism can be described as a force that attracts and repels magnetic objects. This force is mediated by magnetic fields that penetrate different media. Some materials naturally have magnetism as a default property. However, certain materials can be magnetised or demagnetised according to the requirements. What Creates Magnetism in Metals?
