Inductor made with magnet wire wound around a toroidal core. Magnet wire [1] or enameled wire is a copper or aluminium wire coated with a very thin layer of insulation.It is used in the construction of transformers, inductors, motors, generators, speakers, headphones, hard disk head actuators, electromagnets, electric guitar pickups, and other applications that require tight coils of insulated ...
Everlight EL817 phototransistor opto-isolator in DIP-4 package Halo TG110-S050N2RL 10/100BASE-TX Ethernet pulse transformer in SO-16 package, with the underside shown on the right. Galvanic isolation is a principle of isolating functional sections of electrical systems to prevent current flow; no direct conduction path is permitted.
In electrical engineering, electromagnetic shielding is the practice of reducing or redirecting the electromagnetic field (EMF) in a space with barriers made of conductive or magnetic materials. It is typically applied to enclosures, for isolating electrical devices from their surroundings, and to cables to isolate wires from the environment ...
The magnetic properties of electrical steel are tested using the internationally standard Epstein frame method. [18] The size of magnetic domains in sheet electrical steel can be reduced by scribing the surface of the sheet with a laser, or mechanically. This greatly reduces the hysteresis losses in the assembled core. [19]

Magnetic field generated by passing a current through a coil. An electric current flowing in a wire creates a magnetic field around the wire, due to Ampere's law (see drawing of wire with magnetic field). To concentrate the magnetic field in an electromagnet, the wire is wound into a coil with many turns of wire lying side-by-side. [2]
Magnetic field (green) induced by a current-carrying wire winding (red) in a magnetic circuit consisting of an iron core C forming a closed loop with two air gaps G in it. In an analogy to an electric circuit, the winding acts analogously to an electric battery, providing the magnetizing field , the core pieces act like wires, and the gaps G act like resistors.
Three-core copper wire power cable, each core with an individual colour-coded insulating sheath, all contained within an outer protective sheath. An electrical insulator is a material in which electric current does not flow freely. The atoms of the insulator have tightly bound electrons which cannot readily move.
