magnetism, phenomenon associated with magnetic fields, which arise from the motion of electric charges.This motion can take many forms. 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.Magnetism is also associated with elementary particles, such as the electron, …
Electromagnetic theory is a physics field focusing on electric and magnetic fields'' interactions. It shows how charges and currents create forces and electromagnetic waves like light and X-rays, detailing their propagation through space. Electromagnetic theory is based on four fundamental equations, known as Maxwell''s equations, that relate the electric and…
Electromagnetic induction is a fascinating and vital concept shaping how we generate, transfer, and utilize electricity. Its underlying principles, Faraday''s Law and Lenz''s Law, explain the phenomena occurring when magnetic fields interact with conductors. At …

Peter-princippet er opkaldt efter Dr. Laurence J. Peter, og fortæller, at ansatte i en hierarkisk organisation vil blive forfremmet indtil de når deres niveau for inkompetence. [1]Peter-princippet er en gren af hierarkologien, studiet af hierarkier.Ved hierarki forstås enhver organisation, hvis medlemmer er inddelt efter rang, grad eller klasse. [1]
Principles of nuclear magnetism has, over the years, established itself as the classic single volume treatise which gives a comprehensive account of all the concepts, theories, and results associated with the study of nuclear magnetism.

Princippet ved magnetisk behandling af vand er kort fortalt at tvinge vandet gennem en snæver spalte, hvori en magnet frembringer et tværgående magnetfelt. Herved forhindrer apparatet efter sigende kedelsten og kalkaflejringer længere fremme i installationen. End ikke elektriske varmelegemer kalker til, selv om netop varme normalt starter ...

FIFO-princippet, First In First Out, metode til prisansættelse af vareforbrug og varelagre i handels- og fremstillingsvirksomheder.Metoden forudsætter, at de først indkøbte eller producerede varer indregnes først i resultatopgørelsen. Det betyder, at omkostningsforbruget for solgte varer opgøres til de ældste enhedsomkostninger, mens de enheder, som bliver på …
Ampere''s Law. A more fundamental law than the Biot-Savart law is Ampere''s Law, which relates magnetic field and current in a general way. In SI units, the integral form of the original Ampere''s circuital law is a line integral of the magnetic field around some closed curve C …
The attraction of ferrous objects to a permanent magnet has been a source of wonder since the Iron Age. Feeble magnets are widespread in nature in the form of rocks known as lodestones, which are rich in magnetite, an oxide mineral with ideal formula Fe 3 O 4.Rocky outcrops eventually get magnetized by huge electric currents when lightning strikes, and these …

The Earth''s magnetic field probably originated about 3.45 billion years ago and played a vital role in protecting the planet from damaging solar radiation, which may have stripped it of its atmosphere and water, making it completely unsuitable for life as we know it (Tarduno et al., 2010).Though the exact cause of the magnetic force continues to elude researchers, it is …
This article will provide a basic introduction to the principles of electromagnetism and electric motors. As the name suggests, electromagnetism is a branch of physics that focuses on the interaction between electricity and magnetism. It …
Two-dimensional (2D) semiconducting tin disulfide (SnS 2) has been widely used for optoelectronic applications.To functionalize SnS 2 for extending its application, we investigate the stability, electronic and magnetic properties of substitutional doping by high throughput first-principles calculations. There are a lot of elements that can be doped in monolayer SnS 2.
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.Their movement generates an …
Alle stoffer påvirkes i en eller anden grad af et magnetfelt, selv om vekselvirkningen undertiden kan være så svag, at det kræver specialudstyr at påvise den mest kendte materialer, som er magnetiske er jern (Fe), kobolt (Co), nikkel (Ni) og Lanthaniderne med grundstofnumrene 57 til 71.. Til påvisning af magnetisk orden i et materiale benyttes neutronspredning.
Interactive Tutorials. These demonstrations about laws and tools associated with electricity and magnetism allow you to adjust variables at and to visualize invisible forces — which makes them almost better than the real thing.
Princippet for drift af en magnetisk motor er ganske simpelt i teorien. Som vi ved, Modsatte poler af magneter tiltrækker og lignende poler frastøder.. En magnetisk motor bruger denne frastødende kraft mellem magneter til at generere bevægelse. Ved at placere magneter i specifikke arrangementer (typisk på et hjul), får den frastødende ...
