EFFECTS OF ELECTRIC CURRENT 1) Magnetic field and Field lines:- a) Magnetic field :- The region around a magnet where the force of attraction or repulsion can be detected is called magnetic field. Magnetic field around a magnet can be detected by using a magnetic compass. b) Magnetic field lines:- Magnetic field lines are the paths around a magnet along which the north pole of a magnetic compass needle tends to move. The magnetic field lines around a magnet can be observed

Commentary on Field of Autumn Advancing like a silent threat‚ the onset of winter is presented throughout the poem as a season with sinister intent. The “acid breath of noon” approaches in a “Slow” manner‚ as if sneaking up on autumn. The personification of the “acid breath” not only suggests to the reader the fog is murderous‚ but one could be lead to imagine that the fog is poison gas. This is because “Field of Autumn” was published in 1947‚ two years after the Second World War; clearly the memory

James Lenz and Alan S. Edelstein Abstract—Magnetic sensors can be classified according to whether they measure the total magnetic field or the vector components of the magnetic field. The techniques used to produce both types of magnetic sensors encompass many aspects of physics and electronics. Here‚ we describe and compare most of the common technologies used for magnetic field sensing. These include search coil‚ fluxgate‚ optically pumped‚ nuclear precession‚ SQUID‚ Hall-effect‚ anisotropic magnetoresistance

A Home on the Field: To Understand “Any fool can know. The point is to understand.” (Albert Einstein) The attitude towards immigration has been at odds in the United States for quite some time now. It is an issue that has been on the rise as one of the most discussed topics today in our nation’s society and brought to the forefront of public policy. For many experts‚ the defined way of describing the topic is believed as an “action of coming and settling into a country or region where one is

Magnetic resonance imaging (MRI) is a type of scan that produces detailed images of the inside of the body using radio waves and strong magnetic fields without using radiation. An MRI scanner is a large tube that contains powerful magnets. During the scan‚ you lie inside the tube. Almost any part of the body can be examined using an MRI‚ including the brain and spinal cord‚ bones and joints‚ heart and blood vessels‚ internal organs‚ and breasts. MRI scans are safe and painless. Almost everyone

Being an Umpire Little League umpiring is quite different than that of standard umpiring. You are put in a role of authority‚ often over coaches and fans much older than you that don’t take too kindly to some eighteen-year-old kid making the final calls. You have to know rules to a game with endless possibilities and outcomes where literally anything can happen. You have to be able to make judgment calls on close plays where‚ if you end up getting it wrong‚ you’ll get one angry coach running towards

de-magnetise. MAGNETIC FIELD: The area around a magnet where another magnet would feel a force. MAGNETIC FIELD LINES: Show the direction of the magnetic field. The lines run from North to South. Where the field is strong‚ they are close together. INDUCED MAGNETISM: A magnetic material can be magnetised by being placed in a magnetic field. ELECTROMAGNET: A current-carrying coil of wire (SOLENOID) often wrapped around a soft magnetic core which produces a magnetic field quite like a bar magnet

frequency. Coaxial Line was very suitable‚ since it possessed a dominant mode with zero cut-off frequency‚ providing two important characteristics: very wide bandwidth‚ and the capability of miniaturization. The lack of a longitudinal component of field‚ made it more difficult to create components using it‚ although various novel suggestions were put forth. In addition‚ those components would be expensive to fabricate. In an attempt to overcome these fabrication difficulties‚ the center conductor

In another poem “In Flanders Fields” the author John McCrea uses similar echoes he starts us off walking through the fields and then goes onto tell of the death and destruction that happened there. In this final paragraph I am going to cover the language of the words themselves in all of the extract the words are unambiguous and simple. The message is clear so does not confuse the meaning or mood of the portrayed picture‚ similarly in the poem “In Flanders Fields” the language is simple and does

hours of field experience related to my path. This will be completed my final semester at UNCW and will allow myself to get more hands-on experience directed towards my career path. It is also beneficial because all occupational therapy schools In North Carolina require a minimum of 100 observation hours. With this requirement at UNCW‚ I am well over seventy-five percent there in meeting this requirement. I do need to ask my academic advisor more questions pertaining to the 90 hours of field experience
