Magnetic fields

from Carl Friedrich Gauss, who formulated the mathematical proofs of the electromagnetic effect used by Gauss cannons. The Gauss cannons are often called wrongly railguns from various sources, and while they are similar in general concept (ie, a magnetic weapon), differ in operation, since a railgun accelerates the missiles on two rails parallel conductors. The Gauss cannons are in substance identical to the projector mass, albeit on a smaller scale. Kristian Birkeland is commonly considered the

Purpose: The purpose of this lab is to find the magnitude of Earth’s Magnetic field using solenoids. Procedure: For this lab, we used a commercial solenoid with 120 turns that is 46 cm long. We set up the solenoid in a circuit with a battery, ammeter, and variable resistor. The solenoid has a compass in the middle, so that we can measure the variation in the angle. When we close the circuit, we can change the current by adjusting the variable resistor and recording the value from the ammeter. To

enclosed would be 0. This either means that dl and the magnetic field are always perpendicular (cosine 90 = 0), or that the magnetic field itself is 0. Both are impossible and there lies the contradiction. MAXWELL’S CORRECTION Maxwell corrected the equation by adding another term to it. Considering the above example, there is a change in electric field as the current pierces through one surface of the pot and goes out through the other. This field can be expresses

into the magnetic field faster, by increasing the potential V , and we and desire to maintain an orbit with the same radius, then this equation informs us we would have to increase the magnitude of the magnetic field. Alternatively, if we want to increase the radius of the circular orbit we would have to decrease the magnitude of the magnetic field. This equation can alternatively derived as ; the magnetic force Fm acting on a charged particle of charge q moving with a velocity v in a magnetic field

Magnetic resonance imaging (MRI), also known as nuclear magnetic resonance imaging, is a method to create images of the human body. The human body is mostly made up of molecules of water (H20) .The body is made up of 60% hydrogen atoms. The nuclei of hydrogen atoms are composed of one proton (a subatomic particle containing a positive charge). These protons are very sensitive to magnetic fields, and when they begin to spin they produce their own magnetic field. This means that the nucleus of a

Magnetic Therapy Probably one of the largest contemporary trends in the therapeutic world is the use of magnetic therapy. However, it is also one of the least researched modalities, and has very little sound explanation for it's effectiveness. Winning over its clientele with testimonials by everyone from doctors to elite athletes, magnets are making a place for themselves in the health and therapeutic fields. This is accomplished by utilizing many different marketing strategies and very

Nano crystalline magnetic materials exhibit a variety of unusual and remarkable magnetic properties that are not observed in bulk system [1,2]. Magnetic spinel nano ferrites have attracted the interest of the researchers due to their importance in understanding the fundamentals of nano magnetism and their wide range of applications. They found potential applications in biomedicine such as Magnetic Resonance Imaging (MRI), targeted drug delivery, magnetic separation [3-6] and high density data storage

liquid substance that can be controlled at a distance by a magnetic force. To create such a liquid is not as simple as liquefying a magnetic solid. Magnetic solids lose their magnetic properties at the temperature above the Curie temperature of the substance. At that temperature thermal energy overwhelms the tendency of the electrons to align in regions of similar spins. The Curie temperature is well below the melting point of all normal magnetic solids.

8, 2016 Language Arts Measuring Magnetism Magnetism is a very interesting topic. Playing with magnets can be a very fun and interesting thing to do. It is easy to feel a magnetic force when magnets are close together. They are very fun and interesting, but what makes magnets work? Magnetic fields are generated by microscopic rotating electrical charges, according to HyperPhysics. All electrical charges have a specific set of angular motions or spins. The little charges spin very

The charge to mass ratio of the electron is measured by accelerating electrons through a uniform magnetic field with a constant potential difference. The electron moves in the magnetic field and the equation for force of this electron moving can be manipulated to find e/m . Theory: For this lab, the charge to mass ratio of an electron was calculated by shooting an electron into a uniform magnetic field causing the electron to accelerate radially inwards. This causes the electron to feel a centripetal
