Magnet wire is an insulated electrical conductor that is used to create an electromagnetic field. It is most often made from copper or aluminum and can be used in many different applications. Nearly all electricity needs to be routed through an electromagnetic field to make it useful. Magnet wire is a common part of most appliances and devices and is essential to our daily lives.

Copper is the most popular metal to use for magnet wire as it is a very good electricity conductor and can be made in very fine gauges. It is also very durable and can withstand a lot of mechanical stress. Other popular metals to use for magnetic wire include aluminum and silver. Magnet wire is manufactured to a variety of international standards such as IEC, NEMA and JIS. These specifications determine the type of insulation, the diameter and other important technical properties.

The most important property of a magnet wire is its ability to make an electromagnetic field when energized. The coils of copper in a magnet wire act like a pair of bar magnets with distinct North and South poles when current passes through the coils. Magnet wire is typically coiled around a core of steel or aluminum to increase its strength and provide durability.

Another important feature of magnet wire is its flexibility. This allows it to be wound into a coil without damaging the insulation. For this reason, magnet wire is usually lubricated with a low amount of paraffin oil to enable it to be wound with automated machinery. This lubrication does not affect the electrical properties of the magnet wire but it can make a difference in how easy it is to wind into coils.

Magnet wire can also be coated with a varnish-like layer of polyamide or polyurethane. This helps the insulation to stay in place during high-speed winding processes and it also helps to prevent the magnet wire from becoming brittle due to vibrations and other external influences. It can also help to improve thermal transfer and reduce corrosion.

One other important attribute of magnet wire is its resistance to abrasion and chemical damage. This is particularly important for oil and gas applications where magnet wire can be exposed to extremely harsh downhole environments. Traditional workarounds, such as installing wires with thicker insulation, are often ineffective against the extreme conditions in oil and gas downholes. This can lead to unexpected failures and shorter tool run-times which ultimately leads to increased maintenance and downtime and lost production.

Magnet Wire is designed to operate reliably in harsh downhole environments by using a high-performing engineered fluoropolymer insulation that can withstand the most aggressive chemicals and temperatures, providing long tool life for maximum productivity in downhole operations.
