Electric field

designed to teach Ms. Rayburn’s fourth grade class about electromagnets and magnetism. The main point for the students to learn will be that certain metals possess an electromagnetic force and can attract other types of metals by their electromagnetic field. Teaching the students about how electromagnets work and what magnetism will surely get them more interested in STEM education. The children need to understand more about engineering design as well as creative thinking. To accomplish this…

Stray current corrosion: Stray current is the current which occurs when conductors are placed between high magnetic or electric fields. Presence of stray currents over the PCB surface can generate corrosion problems. The below figure 5 shows severe corrosion damage to micro wave module for 24 GHz. This equipment is built in controlled conditions where water condensation is possible. After few hours of use, severe corrosion was seen on the surface. Figure 5. Stray current corrosion of a micro…

They’ll use a nail and a battery to create a magnetic field. It’ll turn the nail into a magnet. Students should be sure to write down their observations throughout the experiment. Students will wrap the center portion of the wire around the nail 10 times so that it forms a coil. They should have extra wire…

Diamagnetism can make levitation possible. How? Diamagnetic materials are repelled by magnetic fields. The most diamagnetic materials are graphite and bismuth. Technically, everything is diamagnetic but the force of it is very weak. Diamagnetism is present in everything, but is only observable if other types of magnetism, such as paramagnetism, ferromagnetism, ferrimagnetism, antiferromagnetism, etc. do not overwhelm it. Most of the time, diamagnetic materials’ effect is very weak. Levitating…

Deadly, wicked, genius, brilliant, and wizard were all used to describe the bright and advanced mind of which belonged to Nikola Tesla. Too advanced for his time, Tesla’s ideas prove to be brilliant in today’s time. Tesla’s inventions and ideas lead to the advancement of society. Tesla believed that electricity could be found all around the world, and that it was easy to access. When Tesla came to America, he met an Indian Guru who taught Tesla about prana. The basis of prana is that energy…

In theory, we can look at the asteroid as one giant particle with a static electric charge. As our asteroid moves rapidly through the air, it now becomes a moving charge. Once it becomes a moving charge, it should be capable of producing a magnetic field, as it produces its own current by moving through the air. The exact magnitude of the field will depend on the speed and charge of the asteroid, which will likely vary at any moment. The fragment entering the earth’s atmosphere is heated to a…

spin. This spin is then determined by its quantum number, which is represented by the symbol S. Each nuclear spin is associated with a magnetic moment. When this moment is placed in an external magnetic field, these spin states differ in magnetic potential energy. If placed in a static magnetic field with a small amount of spin polarisation however, certain radio frequency signals can allow a transition between spin states, with some of the spins being placed in a higher energy state. When the…

(1) What is the hypothesis of this paper and where did you find it? The hypothesis of this paper predicts if low-intensity electric and magnetic fields (EMF) are a method of sensory transduction, then it is expected that that EMF can evoke brain potentials like other sensory modalities. This hypothesis can be found at the end of the Abstract and at the end of the second to last paragraph in the Introduction. (2) Is the writer’s voice passive or active and does he appear in the text? If the…

domains behave like a tiny little bar magnets just like the kind you have probably played with at school. The needle of a compass is also a bar magnet, and we know what this does: it points north because it likes to line itself up with the magnetic field of the earth. "However, if you bring the needle close to another…

Magnets create magnetic fields, which can attract or repel metal objects. Magnets are utilized in motors, circuits, compasses, and can be used in many other applications. They are also used in something called the Gauss Rifle, which can use magnets to launch a projectile at high speed. It is made up of one or more magnet stages, which consists of a magnet and two ball bearings on one side. The number of magnet stages can determine how fast or how slow the projectile can go. It should be noted…
