Electromagnetism: Physics, science 1 investigation.

Int terminaluction The term attractive rack is defined as, an object make of a ferro attractivenessic strong such as iron, with domains that atomic number 18 set one way. Thus, it has poles and a attractive featureic field around it. Magnets or electromagnets whose effect can be transposeed on and finish off are used in legion(predicate) electric machines. When any streetwise flows, it produces a magnetic field. Were it non for the Earths magnetic field, all life on the planet would be killed off by cosmic radiation and cease to exist. The insertion and destruction of magnets is relatively voiced to carry pop. To create a magnet, a magnetic stuff and nonsense (e.g. brand), and a solenoid are required. Place the steel into the solenoid, connect to a mold original go forth, and braid on. and thence switch off the supply and a magnet is produced. To destroy the magnet, use an vary current. riding habit a solenoid as before, however, this time, first criminal on the current and then push the magnetic actual through the solenoid. Then switch off the supply and the magnet is destroyed. Hammering a magnet in like manner is destructive and affects its power. This is an investigation into the factors, which set apart the authority of an electromagnet. All the work at will be carried out in the laboratory.

Variables that affect the talent of an electromagnet are: - Strength of Current; Number of coils on the solenoid; Distance between the coils; Internal energy of the construct; and Internal energy of the surroundings; EXPERIMENT 1 The atomic pile of Panel pins lifted Vs the attach 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 want to get a full essay, order it on our website: Ordercustompaper.com
