Magnetic field

Padilla 11-13-17 Mr. McMahon Period 1 Magnetic field strengths My science project is about homemade electromagnetic magnets and permanent magnets strength on heat and cold temperatures. I'm going to accomplish this by making three sets of electromagnets and permanent magnets in hot temperature, room temperature and cold temperatures to see how would they be affected by the different temperatures its put in. But the dependent variable is on the magnetic field strength. In the next other…

scientists have studied the effects of magnetic fields on human health. In a study of magnetic fields and cancer, “Animal and Cellular Evidence,”[1]. Bo Holmberg compares many studies that apply magnetic fields on mice and rats and he reports the effect of magnetic fields on skin, liver, harmonies, and DNA. He said that studies on animals were effective in proving the extent of exposure from magnetic fields enough to cause some effect. Different studies applied magnetic fields with different…

The mini torsion device that will be designed for this senior design project will apply a torsional load to a small cylindrical sample with a diameter of 5 mm or 6 mm. The device will need to fit under an optical microscope and will not be able to exceed the weight limits of the sample stage on the optical microscope so that Raman microscopy can be performed on the sample while it is under a torsional load. The device will also need to collect data and calculate the angle of twist of the sample.…

mixture. When an external magnetic field is applied, there is a quantized interaction between the magnetic field itself and the magnetic moment of the proton. Thus, the magnetic moment of the proton either applies with or against the magnetic field depending on direction the proton is spinning. In the alpha spin state, the magnetic moment of the proton is applied with the magnetic field, while in the beta spin state, the magnetic moment is applied against the magnetic field. A proton that is in…

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…

such as ring doorbells to surgically pull a steel splinter from your eye (Stringer). There are many factors that may affect the way electricity flows throughout metals. For example, the number of coils wrapped around the metal object may affect its magnetic strength. Another factor may be the size of the battery, because the stronger the battery is, the more power/voltage it contains which enhances the strength of the electromagnet. The way an electromagnet attracts other objects is also majorly…

Every vehicle has a number of electrical instruments. Each one varies due to the certain make and model of the vehicle with the different variations on the particular vehicle. Take a truck for instant it has a speedometer, tachometer, and transmission temperature gauge. Due to the fact that it will be towing a heavy object and be putting stress on the motor, so it doesn’t get too hot the gauge is there to protect it. Now on a sport car your two main instruments will be the speedometer and the…

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…

The History of the Development of the Four Fundamental Forces Nature has a total of four fundamental forces. The forces include gravitational, electromagnetic, strong nuclear and weak nuclear force. Gravitational force is the force of attraction between all masses. Every object in this universe is pulling upon other objects. Many scientists came up with logics to explain the science behind gravitational forces. The first one to try was Aristotle in around 330 BC. Aristotle believed Earth and…

hydrodynamics of a fluid is expressed in the form of conservation laws of mass, momentum and energy.The magnetohydrodynamic phenomena are a consequence of the mutual interaction of the fluid flow and the magnetic field. As is well known, a conductor crossing magnetic field lines gives rise to an induced electric field, which causes an electric current in the conducting fluid. The following are the Maxwell,s equations ∇⋅D = ρcf ∇⋅B = 0 …
