Wrapping the copper wire around an iron nail, increasing the current.   Increase the power going through the wire or have more wire wrapped around the metal object. So in â¦ the case of a nail with wire wrapped around it, the more wraps you do the stronger the electromagnet will be.
Porcupines are a type of rodent found in two main regions of the world, so scientists group them into either Old World or New World porcupines.
Porcupines live in many parts of North America, Africa, and South America. Primary habitats include forests, deserts, and grasslands. In Washington State, porcupines occur mostly in forested areas, but also thrive along riparian zones, in brushy wetlands, and even in the shrub-steppe region of eastern Washington.
