What is the Meaning of the Word Magnetics?

Magnetics refers to materials that attract metals like iron and steel, or something else magnetic in nature such as an attractive rock star with charisma.

Magnets feature north and south poles, which repel similar poles while drawing opposite ones closer together. Only materials with permanent magnetic properties, such as ferrimagnetic materials or ferromagnetism can retain their magnetism to function as permanent magnets.


Magnetics is a broad term that can be applied both literally and figuratively, including its usage figuratively. Magnetics refers to anything that attracts metal like magnets do or someone with charisma. Magnets are composed of magnetic materials like iron and its alloys such as nickel, cobalt and certain steel alloys which are magnetic. Their north/south poles aligned create an attractive/repulsive force on other magnets in a compass by aligning themselves with their north and south poles respectively - similar to magnets' properties when applied figuratively or literally.

Thales of Miletus first studied lodestone properties around 625 BCE; however, navigation did not become possible until 11th century when compass was invented and utilized as an effective navigational aid.

Discrete magnetics, more commonly referred to as power line filters, are designed to protect networking equipment from electromagnetic interference (EMI). By filtering out disturbances that cause electromagnetic crosstalk and can damage cables, switches, routers, or hubs. These types of filters are found throughout all forms of network hardware systems and often play an essential part of system design.


Magnetism refers to the phenomenon by which magnetic forces attract or repel electric currents and other electrical charges. These magnetic forces arise from electrons carrying electric charges revolving around their nucleus in each atom; as their spins change direction they produce an ever-evolving magnetic field which varies in strength with direction of rotation - this is why magnets typically feature two poles, one always facing north while the other always points south.

Ferromagnetic materials, or those which exhibit strong magnetic attractions to magnets, are capable of remaining permanently magnetic or even producing their own magnetic fields, known as "induced magnetism."

Lodestones, rocks with natural magnetism, were once used by sailors to determine their position at sea. Suspending one from a string caused it to "seek", or point northward, hence giving rise to their being known as magnetic lodestones; later adopted into magnetism studies as such.


Magnets attract or repel ferromagnetic objects, and can also produce their own magnetic field when current is applied to them. A magnet's polarity is determined by its north and south poles which always oppose each other; magnets are also rated according to their pull force - how much force it can withstand before demagnetizing completely.

Magnets of considerable size and power are used in industries to write data onto ferromagnetic materials or induce current in wires. Due to their fragility, however, and an array of debris which accumulates within their magnetic field that cannot easily be removed from it's path; large, powerful magnets must be transported and installed with great care when being used commercially.

Magnets are widely used in machines that utilize motors to convert electrical energy into motion, such as fans, washing machines and cars. Magnets work through electromagnetic induction by pushing electrons out of metals that creates currents of electricity; this process is known as electromagnetic induction. Rare-earth magnets can make magnets even stronger; though more expensive than their ferromagnetic counterparts they hold larger amounts of polarization and hold onto it more readily than regular ferromagnetics.


Magnetic materials are distinguished by their ability to attract or repel other magnets. There are three broad groups: ferromagnetic metals such as iron and nickel are most often thought of when people hear "magnet."

Electromagnets use a coil of wire wrapped around a core made of ferromagnetic material connected to an electricity source to form a magnetic field within its coil that can be quite strong; this phenomenon results from moving electric charges amplifying by way of interaction with ferromagnetic materials.

Magnets play an essential role in healthcare, where hospitals use magnetic resonance imaging (MRI) to quickly detect issues in organs without surgery. Magnets also serve a variety of other purposes ranging from characterizing synthesized compounds in chemistry labs to separation magnetic metals from non-magnetic metals in scrap and salvage operations and magnetic levitation transport, suspending, guiding, and propelling vehicles using electromagnetic force. Magnets also find use as children's toys such as the M-tic and Levitron while being utilized in art pieces that can be placed on refrigerators - examples include vinyl magnet sheets adhered directly onto paintings or photographs that create magnetic artwork which can then be placed onto refrigerators as magnets are applied and attached using vinyl magnet sheets directly onto paintings or photographs to produce magnetic artwork that can be placed directly onto refrigerators allowing display on refrigerators.


Magnets play an integral part of everyday life. From toys to credit cards, magnetic stripe readers and MRI machines - magnets have their uses everywhere from simple toys to toys with magnetic strips on them to credit card readers and MRI machines. Magnets come in all sizes from tiny specks barely noticeable under clothing to industrial magnets weighing tons; some are plainly visible while others remain hidden away within appliances or medical equipment.

Magnetism's fundamental properties stem from electron motion and spin within an atom. Their orbital motion confers magnetic properties while their spin creates a magnetic moment proportional to electric current passing through it.

Magnets have the ability to attract or repel other magnets, with each possessing two magnetic poles called North and South poles. Magnets may either be permanent or temporary, with permanent magnets made of materials that retain their magnetism over an extended period, while temporary ones lose it upon exposure to external magnetic fields. Scientists first established a quantitative relationship between magnetism and electricity during the 19th century when Danish physicist Hans Christian Oersted discovered iron atoms could become magnetized when exposed to an electric current, leading them to develop quantitative measures.
