What is special about magnet wire?

What is special about magnet wire?

Magnet wire types can be quite varied but will include the following features: (a) uniformity of insulation, (b) good electrical properties like dielectric strength and insulation resistance, (c) resistance to mechanical stress, (d) resistance to chemicals, solvents, and encapsulating varnishes, (e) thermal resistance.

What is the coating on magnet wire?

Magnet wire coating is applying a coat of electrically insulating varnish or enamel to aluminum or copper wire used in electrical machinery. The wire is usually coated in large plants that both draw and insulate it and then sell it to electrical equipment manufacturers.

Does copper wire attract magnet?

So the short answer is “No, copper isn’t magnetic.” This can quickly be tested by trying to pick up a penny with a magnet. But copper will interact with magnets in fascinating ways.

What is magnetic copper wire used for?

Magnet wire is an insulated copper or aluminum conductor used to wind motors, transformers, generators and any other electrical device where electrical energy is converted to mechanical energy.

What will happen if you use an uninsulated copper wire for making an electromagnet?

The copper wire around an electromagnet is insulated to avoid current flow between the wires. If the wire is uninsulated the current will take a short cut and will not flow multiple times around the core. If the current does not flow as a loop then the magnetic field will not be created.

What is super enamelled copper wire?

SMA Products Super Enamelled Copper Wire. Enamelled Wire is a Copper Wire coated with a very thin layer of insulation. It is used in the construction of transformers, inductors, motors, speakers, and other applications which require tight coils of wire.

What happens when you wrap a magnet in copper?

If you drop strong magnets onto a plate of copper, something remarkable happens: the magnets will slow down before hitting the surface, appearing to levitate slightly, like the copper is another magnetic force pushing them away.

Is the 42 AWG wire the same as the 1950’s?

The relevant tonal factors with 42 AWG plain enamel magnet wire are the same today as they were in the 1950’s and it comes down to wire diameter and ohms per foot within the 42 AWG tolerance. Differences an these specifications affect the size of a coil and resistance of a PAF guitar pickup for a given number of turns and tonally this matters.

Can you use 42 AWG plain enamel wire?

However today 42 AWG plain enamel magnet is not commonly used due to the fact that the plain enamel coating must be sanded off prior to soldering. This added step has made magnet wire with a solderable coating the wire of choice for most all coil manufacturers.

What kind of wire does a Gibson guitar pickup use?

Gibson’s choice of 42 AWG plain enamel magnet wire is logical for a 1950’s era guitar pickup. At the time plain enamel coated magnet wire was commonly used for coil winding and was widely available from a variety of magnet wire makers in the 1950’s.
