A wire is a single, usually cylindrical, flexible strand or rod of metal. Wires are used to bear mechanical loads or electricity and telecommunications signals. Wire is commonly formed by drawing the metal through a hole in a die or draw plate. Wire gauges come in various standard sizes, as expressed in terms of a gauge number. The term wire is also used more loosely to refer to a bundle of such strands, as in 'multistranded wire', which is more correctly termed a wire rope in mechanics, or a cable in electricity.
Wire comes in solid core, stranded, or braided forms. Although usually circular in cross-section, wire can be made in square, hexagonal, flattened rectangular, or other cross-sections, either for decorative purposes, or for technical purposes such as high-efficiency voice coils in loudspeakers. Edge-woundcoil springs, such as the Slinky toy, are made of special flattened wire.
In antiquity, jewelry often contains, in the form of chains and applied decoration, large amounts of wire that is accurately made and which must have been produced by some efficient, if not technically advanced, means. In some cases, strips cut from metal sheet were made into wire by pulling them through perforations in stone beads. This causes the strips to fold round on themselves to form thin tubes. This strip drawing technique was in use in Egypt by the 2nd Dynasty. From the middle of the 2nd millennium BC most of the gold wires in jewellery are characterised by seam lines that follow a spiral path along the wire. Such twisted strips can be converted into solid round wires by rolling them between flat surfaces or the strip wire drawing method. The strip twist wire manufacturing method was superseded by drawing in the ancient Old World sometime between about the 8th and 10th centuries AD. There is some evidence for the use of drawing further East prior to this period.
A magnetic field is the magnetic effect of electric currents and magnetic materials. The magnetic field at any given point is specified by both a direction and a magnitude (or strength); as such it is a vector field. The term is used for two distinct but closely related fields denoted by the symbols B and H, where H is measured in units of amperes per meter (symbol: A·m−1 or A/m) in the SI. B is measured in teslas (symbol:T) and newtons per meter per ampere (symbol: N·m−1·A−1 or N/(m·A)) in the SI. B is most commonly defined in terms of the Lorentz force it exerts on moving electric charges.
Magnetic fields can be produced by moving electric charges and the intrinsic magnetic moments of elementary particles associated with a fundamental quantum property, their spin. In special relativity, electric and magnetic fields are two interrelated aspects of a single object, called the electromagnetic tensor; the split of this tensor into electric and magnetic fields depends on the relative velocity of the observer and charge. In quantum physics, the electromagnetic field is quantized and electromagnetic interactions result from the exchange of photons.

This video is intended for students to watch and pause as they set up the experiment to find the relationship between resistance and the length of a wire.
032 - Magnetic Field of a Wire In this video Paul Andersen explains how current moving through a wire will generate a magnetic field tangent to the wire. As the current increases the magnetic field will increase and as the radius from the wire increase the magnitude of the field will decrease. When the current in parallel wires travels in the same direction the wires will experience a force pulling them together. Do you speak another language?

Sarcoidosis, like many other mystery illnesses have often negatively impacted relationships. For this reason, many relationships don't survive. Life Wire shares the experience of Cecil Ward and his wife Sonya Ru who have hung in there for 22 years. Admittedly, there have been close calls but somehow they managed to hang in there. Listen to his side of the story. Marriage by itself is hard enough but illness can create bitterness, anxieties, fear, anger and at times hatred. It takes a beautiful soul to forgive such daggers.... there's beauty in us all, we just have to free it.

Join us to learn how you can improve any relationship: work, career, personal, family, you name it. Make no mistake, this is a vital skill that can be learned and applied in a mindful way to improve your emotional intelligence and overall all of your relationships. We will cover “mindfulness” as it applies to interpersonal relationships and the science behind this assertion. Myth or Truth? A lot of people think of our emotional health is being biologically based. Answer: Both! There is a lot of science to support the idea that it actually exists in response to our relationships. We will cover anecdotes and stories that exemplify this, including how FBI negotiators and how they're trained to be better listeners so they can solve any crisis.
