affect with electric and magnetic fields. The electromagnetic force is carried by the photon and is responsible for atomic structure‚ chemical reactions‚ the attractive and repulsive forces associated with electrical charge and magnetism‚ and all other electromagnetic phenomena. According to Coulomb’s Law‚ we know electric charges get Coulomb force in the electric field while current receives another applied force‚ which is Ampere force when it is in a magnetic field. Overall‚ electromagnetic force

excitement shined through her eyes as she told me about the patients who have changed her life. With that excitement there was also a sadness in her voice as she told me about the patients she was unable to save. In the 1940’s nursing was a much different field than it is today‚ she remembers when penicillin was first introduced. Nursing in her day was much about the patient care and building relationships with the patients you were caring for. Having patients that you had a connection with‚ conversations

Universe and Inverse are closely related‚ for the effects of known forces of universe are inverse in nature. Ever since Newton made a bold proposition that there is a force of attraction amongst the planets of planetary system‚ amongst different planetary systems and amongst the different galaxies and varies as Inverse Square of their distances‚ people began to correlate every activities of nature and predict its effect accurately. 1.

Required Vocabulary – IB 12 Higher Level Physics and Physical Measurement 1. Fundamental Units – seven basic units of the SI measurement system: kilogram‚ second‚ mole‚ meter‚ ampere‚ Kelvin‚ candela. 2. Derived Units – units that are combinations of fundamental units. These combinations may or may not have a separate name. (eg. 1 kg m/s2 = 1 N) 3. Accuracy - An indication of how close a measurement is to the accepted value (a measure of correctness). 4. Precision - An indication

1. What does the grounded study approach mean? Grounded theory relies usually relies on qualitative field observations. This means the data comes from observations on the field‚ not theoretical or following a deductive approach. 2. What group would you be interested in studying and why? What types of questions or issues‚ in particular‚ would interest you? I would be interested in learning how gangs operate‚ specifically what kind of organization they have. I don’t think most gangs are as organized

a changing electric current is surrounded by an associated changing magnetic field‚ which in turn generates a changing electrical current in a conductor placed within it‚ which has its own magnetic field…and so on. It is the electromagnetic equivalent of nesting Matryoshka dolls. Thus‚ in the case of electromagnetic induction‚ placing a conductor in the magnetic field surrounding the first current generates the second current. Electromagnetic induction was discovered independently by Michael Faraday

or direct current generator generates a voltage when speed and flux are met. This machine is called a unidirectional (dynamo).It consists of the same basic elements as a simple AC generator like the multi-turn coil rotating uniformly in a magnetic field .The output of which is a series of emf pulses‚ all in the same positive direction resulting in an average EMF developed across the load. Increasing the number of coils thereby smoothen the output providing more pulses at each revolution. The generated

Anti Collision Pad for Vehicles Objective: To be able to use the concept of electromagnetic repulsion in avoiding road accidents. Problem: Is electromagnetic force of repulsion enough to avoid impacts.? Introduction: Maglev Train‚ a train that uses the repulsion of like charges within its railings in order for it to levitate and move‚ was the inspiration of this project. The team thought of some ways to use the concept and build something useful. Until‚ the group thought of some serious road

magnetic field around the conductor. It was then discovered that this effect could be enhanced greatly by winding the conductor into a coil. The effect proved to be two-way: If a conductor‚ maybe in the form of a coil was placed in a changing magnetic field‚ a current could be made to flow in it; this is called induction. So imagine a coil‚ and imagine that we apply a voltage to it. As current starts to flow‚ a magnetic field is created. But this means that our coil is in a changing magnetic field‚ and
