Wiegand Wire For Wiegand Sensor Vicalloy Wire Diameter 0.50mm In Stock Made In China

Wiegand wire

Wiegand wire is produced from a Vicalloy wire. Vicalloy is a permanent magnetic Fe-Co-V alloy. The wire is named after its inventor. At the beginning people use a special process to produce Wiegand wire, annealing a spool of Vicalloy wire and then simultaneously stretching and twisting the wire. This aggressive cold working alters the crystalline structure of the metal and creates two regions-an inner core and outer shell-with significantly different levels of magnetic coercivity. The special process was kept as a business secret for years and was then sold to POSITAL in 2013.

Xunshi managed to find an easier way to produce Wiegand wire and it turned out to be equal in performance. The new method does not require a complicated device to stretch and twist the wire, but succeeded to make the wire to become two layers-an inner core and outer shell, which makes the Wiegand effect happen.

As an expert in high performance alloys, Xunshi are always engaged to the development and research of Cobalt alloy and Nickel alloy, either for the material itself or the applications of material in various industries and areas.

After the special process conducted, the wire exhibits a very large magnetic hysteresis: If a magnet is brought near the wire, the high coercivity outer shell excludes the magnetic field from the inner soft core until the magnetic threshold is reached, whereupon the entire wire-both the outer shell and inner core-rapidly switches magnetisation polarity. This switchover occurs in a few microseconds, and is called the Wiegand effect.

Wiegand effect

The Wiegand effect is a physical phenomenon discovered in the 1970s by John Wiegand, an American inventor who found that by repeatedly stretching and twisting a piece of ferromagnetic wire, he could alter its magnetic properties. When a sample of Wiegand wire is exposed to a reversing external magnetic field, it will initially retain its original magnetic state. However, when the strength of the external field reaches a critical threshold, a region of the wire that is magnetically soft will undergo an abrupt reversal of its polarity. This transition takes place within a few microseconds and can be harnessed to induce a pulse of electric current in a fine copper coil wrapped around the wire.

The electric pulse generated by a Wiegand wire is very brief, but its strength stays nearly constant, regardless of how quickly or slowly the external magnetic field changes. This is what makes the Wiegand effect special: While simple dynamos, which also use electromagnetic induction, are effective at converting rotary motion into electrical energy, their output power varies with rotation speed. When a dynamo is turned slowly, power levels can be too low to be useful. With a Wiegand wire, however, the amount of electrical energy generated with each reversal of the magnetic field remains consistent over a wide range of speeds.

The combination of a short length of Wiegand wire and a surrounding copper coil is referred to as a Wiegand sensor. These are available commercially from UBITO in surface-mountable device (SMD) packaging.

Wiegand sensor

Wiegand sensors are magnetic sensors that make use of the Wiegand effect to generate a consistent pulse every time magnetic field polarity reverses and therefore do not rely on any external voltage or current. The consistency of the pulses produced by Wiegand sensors can be used to provide energy for low-power and energy-saving applications. Being self-powered, Wiegand sensors have a potential in IoT applications as energy harvesters, proximity sensors, and event counters.
