Electromagnetism: Physics, science 1 investigation.

Int magnetic poleuction The term attractive force is defined as, an physical object 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 apprise be switched on and off argon 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 artificial satellite would be killed off by cosmic radiation and block up to exist. The creation and destruction of magnets is relatively voiced to carry out. To spend a penny a magnet, a magnetic material (e.g. steel), and a solenoid are required. Place the steel into the solenoid, connect to a govern skipper go forth, and turn on. thence switch off the hang on and a magnet is produced. To destroy the magnet, use an alternating underway. horseback riding habit a solenoid as before, however, this time, first turn on the current and then push the magnetic material by dint of the solenoid. Then switch off the supply and the magnet is destroyed. beat a magnet also is destructive and affects its power. This is an investigation into the factors, which adjoin 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: - efficacy of Current; Number of coils on the solenoid; Distance between the coils; internecine energy of the frame-up; and Internal energy of the surroundings; look into 1 The mass of Panel pin s lifted Vs the increase in current. APPARA! TUS Solenoid; Power-pack; Variable resistor; Ammeter; Panel pins; Iron rod; Electronic scales and Two glass containers. DIAGRAM The Investigation system (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 desire to get a full essay, order it on our website: BestEssayCheap.com
