does copper attract lightning

The highly conductive copper and aluminum materials used in a lightning protection system provide a low resistance path to safely ground lightning’s dangerous electricity. A lightning rod is a metal strips or rods, usually made of copper, used to protect buildings or structures from a violent lightning strike. In a lightning protection system, a lightning rod is a single component of the system. The short answer is no, metal roofing is not dangerous and does not naturally attract lightning strikes. The purpose of lightning rods is often misunderstood. Myth: If trapped outside and lightning is about to strike, I should lie flat on the ground. It connects to a huge piece of copper or aluminum wire that's also an inch or so in diameter. Metal does not attract lightning, at least not in the way some people think. The basic thing to know about lightning is that it always looks for “ground”. A piece of metal sitting on your roof is not grounded, so it would not tend to attract lightning. The misconception that metal roofs attract lightning is probably because metal itself is known as a good conductor of electricity, and people, therefore, assume that a metal roof must attract lightning. One of the frequently asked questions about weathervanes is whether they attract lightning, and if they are safe when mounted on the roof. You can ground your weathervane with lightning conductor cable, which is NOT sold in any store or home building center. The answer to the first question is “No, weathervanes do not usually ‘attract lightning’ and actually less than a TV antenna does.” If you look around (or remember back a few years), you will see lots of houses with large skeletal TV antennas on them. Think of a pool the size of football stadiium, or much, much larger. Fact: Lying flat increases your chance of being affected by potentially deadly ground current. Generally speaking, metal roofing is quite safe. In reality, when lightning strikes, it is seeking a path to ground and almost always will strike whatever object is highest in the area that also has a direct path to ground. A weathervane contructed of copper or aluminum does not make it a target. It holds no extra attraction to lightning. These materials and components are UL-listed and specially manufactured for lightning protection. If you are caught outside in a thunderstorm, you keep moving toward a safe shelter. Lightning will strike when and where it wants to. Typically, these antennas are grounded but not part of a lightning protection system. The lightning rod is connected with a cable to the earth below, where it can channel the charge to a safe place. Many people believe that lightning rods "attract" lightning. Does Lightning Rod Attracts Lightning In Murrieta? While metal does not attract lightning, it does conduct it so stay away from metal fences, railing, bleachers, etc. If you have a weathervane on a structure it’s possible for it to get struck by lightning. Extreme air currents, up drafts and such, create an enormous pools of negative charge in the sky. The wire is connected to a conductive grid buried in the ground nearby.
