Electromagnetism and it’s Impact on our Health Car By: Dalia Newman Course: Grade 12 Physics Teacher: Mrs. Chocron Due: Friday April 15 2011 Electromagnetism and it’s Impact on our Health Care Electromagnetism is one of the four fundamental interactions of nature. It is the force that causes the interaction between electrically charged particles; the areas in which this happens are called electromagnetic fields. It

variable gap magnet there were two small magnetic disks. One arm of the magnet was unscrewed and removed from its housing. A meter stick was placed on the and the arm was on its side parallel to the meter stick. The Gauss-Tesla meter was used to measure the field strength of the magnet. The probe attached to the meter was perpendicular to the meter stick. There were 4 steps to this process: a. The field strength was measured with the probe flat against the magnetic disk b. The probe was moved one centimeter

phone. In his exhausted state‚ he wished the phone would just begin charging itself as soon as it was brought into the house. So‚ Soljačić started searching for ways to transmit power wirelessly. Soljačić found magnetic resonance a promising means of electricity transfer because magnetic fields travel freely through air yet have little effect on the environment or‚ at the appropriate frequencies‚ on living beings. Working with MIT physics professors John Joannopoulos and Peter Fisher and three students

One of the main issues was its narrow bandwidth due to the cut-off frequency characteristic. Later‚ researchers try to find components that could provide greater bandwidth and possible miniaturization‚ and therefore they examined

will be investigated. Theory: Faraday’s law of induction states the induced emf or voltage in a coil is proportional to the rate of change of magnetic flux through a coil‚ this is shown blew: Ƹ= -dɸ/dt Equation 6.1 The flux of the magnetic field is defined and the following: ɸ=BAcosΘ Equation 6.2 B is the magnetic field at the location of the coil. A is the cross sectional area of the coil‚ and Θ is the angle between the field and the area A. There is several

appliances‚ and toys in every room in your home. They are a very important and vital part of modern life. Have you ever played with magnets before? If so‚ you are well on your way to understanding how simple electric motors work. Magnets have a magnetic field with a north pole and a south pole. If you play with two magnets and try to push the north poles of each magnet together‚ the magnets will not go together. They will repel each other. The same thing happens if you try to push two south poles

Lecture notes by Prof. A. K. JAIN‚ IIT ROORKEE CHAPTER 13: The Deuteron (Lecture time: 2 Hours) Deuteron is the simplest nuclear system where nuclear forces come into play. It is the “Hydrogen Atom” of nuclear physics. It may also be viewed as the simplest odd-odd nucleus‚ having one proton and one neutron. It exhibits features which require the use of a number of new concepts such as exchange force‚ tensor force etc. Of three possible states of two nucleon system‚ di-neutron‚ di-proton‚ and deuteron

Evaluation of velocity gradients‚ temperature gradients and concentration gradients across the plate is done. Observations and discussions of the effects of various parameters on flow variables are done. The non-dimensional parameters observed and discussed are Hall parameter‚ M; Magnetic number‚ M 2; Eckert number‚ Ec; Rotational parameter‚ Er; Suction parameter‚ S
