Magnetic field

Magnetic propulsion Magnetic propulsion refers the use magnetic energy to move objects from one point to another. Due to increased demand for clean energy, the use of electromagnetic propulsion will also be a new way of powering the future vehicles. This method employs the use of electrical current to create an opposing magnetic field that results in repulsion. The electromagnetic propulsion has been in use in motors to create a rotational force which drives the vehicles wheel forward. However…

by the rotation of the sun and escape through holes in the magnetic field” (The Northern Lights Centre). It is this outer layer which reveals evidence of sun spot activity and coronal holes, as they appear darker in photographs and x-rays of the sun. This corona ejects streams of magnetized plasma, consisting primarily of helium nuclei, protons and electrons (38 Moldwin). For these particles to be able to escape the sun’s gravitational field, they need to have enough energy and be travelling at…

the palliative treatment of spinal bone metastases. This allowed to test the geometrical accuracy of the system on real patients. The vertebra is easily visualized on the integrated megavoltage imaging system and allows for accurate comparison of field co-ordinates with MRI co-ordinates. The system was accepting patients since around 2012. (Ref 4). The individual MRI-Linac procedures were very reproducible, on average taking 41 min (range 33–44 min) and were well tolerated by the patients. This…

substantially increased rates of therapeutic success compared to conventional remedies. Due to the immature integration technology, the development of the fully functional NeuRobot is rather challenging. However, owing to the scientific advancement on the fields of nanorobotic manipulation, it is predicted that the most critical elements of the treatment will reach a sufficient technological maturity to produce the fully functional NeuRobots. In light of all the unprecedented benefits, the…

Modern developments in technology and medicine have made studying the brain much easier that it used to be. Although the brain is encased in the skull, there are still many ways we can find out how it works. One of the simplest ways we can study the brain is through case studies. A case study looks at one specific situation and tells how that particular individual reacted and how his or her brain was affected. A couple downsides to the case study is that there is usually information missing and…

On April 14th, 2015, scientists reported the comet's nucleus has no magnetic field of its own. On September 30th, 2016, the Rosetta mission was ended in an attempt to land on the comet's surface. In total, the mission lasted for 12 years, 6 months, 28 days. During the mission, there were lots of important firsts. Rosetta was…

he was able to confirm the existence of a pattern, a repeating cycle. But Wolf detected an 11 years cycle not a 10 years cycle. 11 years cycles? Does that sound familiar to anyone? No? Well, geomact activity, the nature variations in Earth's magnetic field, it fluctuates in a 11 year cycles. Well, we'll cover this Later in this semester. But for heard of the sunspots' cycle was also 11 years, well, they just had to find out what was going…

With the discovery of water on Mars, the life expectation on Mars is increased in the minds of people. According to NASA, it is found that early atmosphere of Mars was as thick as or even thicker than Earth’s atmosphere today. NASA has also discovered that the air on Mars, whatever is left, is leaking into the space at a speed of half a pound per second. The new readings taken by NASA’s Mars Atmosphere and Volatile Evolution mission, shortly known as Maven, show that whenever a solar storm hits…

future. Electromagnetic railguns are long range weapons that fires projectiles (electrically conductive) with electricity. The current supplied to the rails which flows up one rail and down the other induce a magnetic field around both rails as shown in Figure 2. The direction of the magnetic fields are obtained using the…

recorded having compass malfunctions, he saw a fireball crash into the ocean, he witnessed strange lights and odd weather phenomena when passing by this area…” (Ancient Code). Columbus reported his compass was off, which would explain that the magnetic fields were off. Also he reported odd weather, which could have been methane bubbles rising to the surface. He also reported strange lights and a fireball crashing into the ocean. This could have been the works of aliens and the fireball was an…
