An electromagnet is made by wrapping insulated wire around a steel nail and connecting the wire ends to a dry cell battery. If you want this electromagnet to reverse its north and south poles, then you should reverse the current flow. wrap the nail the opposite way. reverse the current flow AND wrap the nail the opposite way. reverse the current flow OR wrap the nail the opposite way, but not do both. point the nail in the opposite direction.

What is North And South Poles?

The North and South Poles are the two ends of the Earth, both located at extreme latitudes. The North Pole, located in the Arctic Ocean, is surrounded by land and is sometimes known as the geographic or true north pole. Meanwhile, the South Pole is in Antarctica and is also referred to as the magnetic south pole. Both poles have had a great impact on human history, from exploration to navigation to scientific discovery.At the North Pole lies an area rich with natural resources such as oil and gas reserves which has attracted many nations for their own economic gain. The surrounding area also provides habitat for several species of wildlife including polar bears, walruses and narwhals. In addition to its resource-rich environment, it serves as a major air traffic corridor between Europe and Asia due to its unique location at the top of our planet. As a result, it has been an important center of exploration since early explorers sought out routes across this region in search of new lands and resources. The South Pole’s location on Antarctica makes it an even more difficult place to explore compared to its northern counterpart due to harsh weather conditions year-round. Despite these challenges however, humans have still managed to make incredible discoveries here too such as meteorites that are believed to be over 4 billion years old. This place has also been used for research purposes since 1957 when a US research station was established there dedicated towards furthering scientific knowledge about our planet like understanding climate change or observing deep space phenomena like supernovas from up close. The North and South Poles represent two very different parts of our world but together they form one unified planet full of amazing secrets waiting to be discovered. With advancements in technology giving us better access than ever before now is definitely an exciting time for researchers seeking out new knowledge about Earth’s most mysterious places.
