Electromagnetism is creating a revolution aboard U.S. Navy ships. First the navy unveiled its first gun that utilizes this energy to accelerate projectiles earlier this year. By using electromagnetic energy, the project can be accelerated to higher speeds than a bullet in a conventional gun. It can also fire such projectiles over an impressive 100 nautical miles. Such weaponry marks the first true advancement in the actual method used to accelerate project weapons since the earliest form of primitive muskets. Certainly the speed of fire and loading of guns increased incredibly over the past century and more, but they always relied on a chemical explosion to accelerate the projectile down the barrel.
The navy is now using electromagnetism in
The Trident Submarine houses twenty-four nuclear warheads with each having a range of 4,600 miles over land. If a nuclear war were to break out between the Soviet Union and the United States, virtually every major city could be destroyed in a matter of hours. The origin of these major players in modern day warfare lies in the Revolutionary and Civil Wars.

Many different types of weapons or weapon improvements were made during the First World War. Both sides had great minds working on their weapons in an effort to give their respective sides an upper hand. One weapon that had a devastating impact was the machine gun. Based upon earlier models in the late 1800’s, the machine gun was now better than ever before. With a fire rate of 450-600 rounds per minute, this was a weapon to be reckoned with. It could easily mow down rows of approaching enemies, making advancements in trenches nearly impossible.
Finding its origins in Hiram Maxim’s early designs in 1885, the machine gun as we know it began to take root. Utilizing a mechanism in which the force from a fired round would eject itself and load the next in rapid succession proved to be an invaluable asset. Gone were the days of a slow and methodical reloading process that
When World War one broke out the need for newer and more efficient firepower was required to outdo their opponent in the race of technological weaponry. New exciting, but absolutely devastating weaponry was tested on the battlefield and proved extremely fatal for the receiving end.
In the world, there are currently over 140 nuclear-powered ships, each of which is powered by more than 180 miniaturized nuclear reactors. Although most of them are submarines, they can also range from icebreakers to aircraft carriers. While there have been many people to contribute to the research and development of nuclear propulsion, none of them have been more influential than Admiral Hyman George Rickover, known as the “Father of the Nuclear Navy.” Accomplished in his naval career, he was a staunch defender of freedom from all who sought to undermine the sovereignty of the United States, or who would threaten our security. Though a controversial issue at the time, Admiral Rickover was passionate in his insistence for the development of
Inside The Guy Magnet System James Scott teaches you exactly how to do it the right way, and more specifically, here are some of the things that you can expect to learn by purchasing his guide:
Conventional guns, such as cannons, 155 mm howitzers, and multiple-launch rocket system (MLRS), utilise the chemical energy derived by igniting a charge of chemicals (gun powder). The maximum velocity at which the penetrator can be propelled is approximately 1.5-2.0 km/sec. On the other hand, electromagnetic launchers (EML guns), or railguns, use the electrical energy, and the concomitant magnetic field (energy), to propel the penetrators/projectiles at velocities up to 10 km/sec. This increase in velocity results in greater kinetic energy for the same penetrator mass. The greater the energy, the greater is the damage inflicted on the target. For this and other reasons, the DoD (especially, the U. S. Army) has conducted extensive research into the railguns.
Rauen (2016) wrote that certification demonstrates that the nurse has the knowledge and skills beyond the basics in the specialty area. The patient, physician, and nurses expect a higher standard when a nurse works in a dedicated field. When a nurse is working in a focused field, more knowledge needs to be obtained to understand the nature and complexity of the disease. The professional certification shows others that there is acknowledgment of quality of care. As hospitals and nurses become more competitive, this standard is raised and consequently a higher quality of care is expected. And, one way of designating high quality of care is through certifications. Professional certification is recognized by American Nurses Credential Center’s (ANCC’s) Magnet Recognition Program for excellence in nursing services. According to the ANCCs (2017), The Magnet Recognition Program’s goals and guiding principles are to promote quality, identify excellence and disseminate best practices. With a hospital having a Magnet status, this will attract and retain top nurses, improve patient care, foster a collaborative culture, and advance nursing standards and practice.
The floating car is a complex machine and there are many parts to it. Magnets are the the most important part of the car. Thay are the objects that hold up the car up in a floating position. Air propulsion is the thing that moves the car in whatever direction it is going. Fans or some other type of objects that creates some sort of thrust with air will be used.

A magnet is any object that exhibits magnetic properties by attracting iron-containing objects and by creating a magnetic field. During 600 B.C. the Greeks were the first to use magnets when they encountered a mysterious stone that attracted iron and other similar material. Magnets attract ferrous objects such as iron, cobalt, nickel, and steel (How Magnets Work). Every magnet has a north and a south pole. The end that points to the North is called the North Pole while the pole that points South is called the South Pole. Opposite poles attract each other. Therefore, the North Pole of a magnet will attract to the South Pole of another magnet. On another note, same poles repel each other. Therefore, two North Poles will repel each other (Reis).
Essentially every single device that humans use to make their life easier can be greatly attributed to the field of physics for its inception. The laws of physics govern everything that we use, see, and observe life as we know it would not be possible without it. Multiple branches of physics exist, but one stands out as the branch that has the most promise to deliver devices well beyond even our wildest imagination, electricity and magnetism. Someone who has not been educated a great deal on the topic usually will not realize how big of a role electricity and magnetism play into their everyday life, and even life on earth. The phone they carry in their pocket, the invisible magnetic field of the earth keep life sustainable, and even the electrical signals that his or her own heart uses to pump blood to distribute throughout the body are all applications of the physical laws of electricity and magnetism. On the horizon lie endless amounts of other futuristic applications that physicists and engineers work tirelessly day after day on. If science is correct in its predictions of the future, electricity and magnetism will play a monumental role in shaping life on earth in the not so distant future.
A firearm, in the most basic form, consists of a barrel, an action, a firing mechanism, a stock and a sighting device. No matter the form of the firearm, the same basic principles of physics and chemistry apply. The study of these principles is called ballistics. There are three types of ballistics, internal, external, and terminal. Internal ballistics is the study of the flight of a projectile inside a firearm. External ballistics is the study of the flight of a bullet after leaving the muzzle and until it hits the target. Terminal ballistics is the study of the effects of a projectile on a given target. Because this essay deals with the flight of the bullet, terminal ballistics will not be discussed.
Temperature has a large effect on particles. Heat makes particles energized causing them to spread out and bounce around. Inversely the cold causes particles to clump together and become denser. These changes greatly F magnetic the state of substances and can also influence the strength of magnetic fields. This is because it can alter the flow of electrons through the magnet.
