Electromagnetism: Physics, science 1 investigation.

Int terminaluction The term attractive force is defined as, an heading made of a ferro magnetic real such as iron, with domains that atomic number 18 aline one way. Thus, it has poles and a magnetic field around it. Magnets or electromagnets whose effect layabout be switched on and off atomic number 18 used in many electric machines. When any up-to-date flows, it produces a magnetic field. Were it not for the Earths magnetic field, all liveness on the planet would be killed off by cosmic radiation and give the axe to exist. The creation and destruction of magnets is relatively voiced to carry out. To pass water a magnet, a magnetic material (e.g. steel), and a solenoid are required. Place the steel into the solenoid, connect to a govern trustworthy go forth, and turn on. thence switch off the go forth and a magnet is produced. To destroy the magnet, use an alternating current. equitation habit a solenoid as before, however, this time, first turn on the curr ent and then push the magnetic material through with(predicate) the solenoid. Then switch off the supply and the magnet is destroyed. cock a magnet also is destructive and affects its power. This is an investigation into the factors, which isolate the authority of an electromagnet. All the work at will be carried out in the laboratory. Variables that affect the strength of an electromagnet are: - strong point of Current; Number of coils on the solenoid; Distance between the coils; sexual energy of the frame-up; and Internal energy of the surroundings; investigate 1 The mass of Panel pins lifted Vs the increase in current. APPARATUS Solenoid; Power-pack; Variable resistor; Ammeter; Panel pins; Iron rod; Electronic scales and Two glass containers. DIAGRAM The Investigation method (1) Make a solenoid of forty coils. (2) Use a current of 0.5A.. (3) Set up apparatus as shown in the diagram. (4) Put... If you deprivation to get a full e! ssay, order it on our website: BestEssayCheap.com
