Don't forget, you are not going to be experimenting with building the coils and such (unless you want to do some serious rewinding), 42 AWG plain enamel wire is perfect for these special electrical projects. It is such a tiny wire that can transfer power through small devices. This wire is a superhero so it can still function well when it is hot.
This wire is able to withstand hot temperatures without losing its electrical conductivity. This indicates that you can still use this wire on a hot day, like at the beach. This matters because when the wire can’t handle the heat, we don’t have devices when we need them.
42 AWG wire is thin so we could use detailed designs & tight connections. Now imagine trying to thread a needle with something like a thick piece of yarn. That yard could be difficult to pass through the small gap in the needle. A fine piece of thread, such as a length of 42 AWG wire, might make it considerably simpler to join those little domains in our electronic devices.
This wire is protected from rust or wear with the plain enamel coating. Just like we wear sunscreen and suntan lotion to protect our skin from the sun, this coating protects the wire in the long run. This makes the wire more durable so our devices will continue to function properly.
This type of wire is frequently used in circuit boards, sensors, and other small devices. So though the internet is a vast web of information, we have to rely on electronic circuits to think for these devices. Sensors allow devices to sense things such as temperature or motion. These devices are able to maintain connectivity and perform effectively with 42 AWG plain enamel wire.
