Im Not Scared by Niccolò Ammaniti Essay -- Gabriele Salvatores Film
Niccolà ² Ammaniti's novel and Gabriele Salvatores' homonymous film "I'm Not Scared" have had their share of popularity in North America if not by gaining a conspicuous readership/spectatorship by travelling into the publicity-wagon of international distributors.1 The formula adopted by both writer and filmmaker appealed to investors as a marketable recipe and yet it failed to magnetize the scattered reader/viewer beyond a short flight-of-entertainment.2 The elements at play in the novel and film are quite remarkable for their traditionally universal appeal.3 The fates of two adolescents, one jailed the other unwilling jailer, intersect and are soon bound together in a struggle for survival at the hands of unsuspecting enemies. The filmmaker's aim was to adopt a child's unadulterated point of view in referential opposition to the surrounding adult world. Given the suspenseful plot and the exploration of the young protagonists' fears at coping with a habitat they must disavow, such an aim and narrative scheme were expected to gather much attention.4 The pre-teens Michele, the novel's principal hero, and Filippo the kidnapped child are ultimately elevated from a pit of dirt and fear, the antechamber of death, chiefly by their own heroic praxis. Yet the problematic lack of any meaningful degree of depth in the novel and film seems to lie precisely with its overly schematic construction, tailored to safely weather the otherwise unpredict able market. The proscription from any domain of memorable works may be due to a major problem both in the novel and film: the ambiguous point of view adopted. The novel is geared for a transposition to the screen. It is no coincidence that the film was scripted by Niccolà ² Ammaniti, who adapted ... ...Little Boy, Don't Look Down". 6 In the novel it is told that the story of Lazarus is learned at school from the schoolteacher, Signorina Destani, p. 83. 7 In fact the entire novel is set in the first person with Michele's voice assuming the narration in the initial race held with his neighboring peers. The incipit reads: "I was just about to overtake Salvatore when I heard my sister scream." 8 207. 9 Compare pages 155-157, 201-203 of the book with the same scenes in the film. 10 The effects of a filmic memory on the written word have been reason for study/confession of contemporary novelists. See Cohen, Keith, ed. Writing in a Film Age: Essays by Contemporary Novelists. 11 See Paul Ginsborg's A History of Contemporary Italy, 383-405. 12 In the film the date 1978 appears superimposed in the opening sequence. 13 Quoted by Frank Bruni.

Solenoids – Physics coursework
Solenoids Permanent Magnet- Magnetic Field.http://www.diracdelta.co.uk/science/source/m/a/magnetic%20field/source.html Magnets have two poles called North and South.Similar (like) magnetic poles repel. Unlike magnetic poles attract. A magnet attracts a piece of iron. The most important of the two properties of attraction and repulsion is repulsion. The only way to tell if an object is magnetised is to see if it repels another magnetised object. The strength and direction of a magnetic field is represented by magnetic field lines. Field lines by convention go from North to South. A magnetic field is three-dimensional, although this is not often seen on a drawing of magnetic field lines.Electromagnets A magnetic field exists around all wires carrying a current. When there is no current the compass needles in the diagram shown line up with the Earth's magnetic field. A current through the wire produces a circular magnetic field. See what happens when there is a current in the wire. The magnetic field for a coil of wire is shown below. The magnetic fields from each of the turns in the coil add together, so the total magnetic field is much stronger. This produces a field which is similar to that of a bar magnet. A coil of wire like this is often called a solenoid.http://www.bbc.co.uk/bitesize/standard/physics/using_electricity/movement_from_electricity/revision/1/slideshow-1/2/An electromagnet consists of a coil of wine, through which a current can be passed, wrapped around a soft iron core. This core of magnetic material increases the strength of the field due to the coil. ââ¬ËSoftââ¬â¢ iron is easily magnetised, and easy to demagnetise- it does not retain its magnetism after the current is switched off. Steel, on the other hand, is hard to magnetise and demagnetise, and so it retains in magnetism. It is used for permanent magnets. The strength of an electromagnet depends on:The size of the current flowing through the coil The number of turns in the coil The material inside of the coil Heinmann physics Domains ââ¬â http://hyperphysics.phy-astr.gsu.edu/hbase/solids/ferro.html#c4Ferromagnetic materials exhibit a long-range ordering phenomenon at the atomic level which causes the unpaired electron spins to line up parallel with each other in a region called a domain. Within the domain, the magnetic field is intense, but in a bulk sample the material will usually be unmagnetized because the many domains will themselves be randomly oriented with respect to one another. The main implication of the domains is that there is already a high degree of magnetization in ferromagnetic materials within individual domains, but that in the absence of external magnetic fields those domains are randomly oriented. A modest applied magnetic field can cause a larger degree of alignment of the magnetic moments with the external field, giving a large multiplication of the applied field.FerromagnetismIron, nickel, cobalt and some of the rare earths (gadolin ium, dysprosium) exhibit a unique magnetic behavior which is called ferromagnetism because iron (ferrum in Latin) is the most common and most dramatic example.
