In simple terms, junkyards are the fields where junks are collected and stored for the purpose of resale. Many times we see many of the cars and other automobiles that are in very horrible conditions and we think that there exists no chance of getting something useful for us. But we are wrong, because all the part of those automobiles and cars are not in damaged condition like the cars and the automobiles as a whole. The place where the cars, motor vehicles and other scrap and metallic parts which are in very bad condition are kept in those yards. The reason behind the existence of these junk yards are that although the finished product (like the cars, motor bikes and vehicles) get damaged very badly but some parts of it may remain in a very good condition. Those parts can be used for new model vehicles for the successful operations by spending less money as compared to purchasing of the new parts. Today these junk yards become the basis and play a very important role in the modern transportation and automotive industry.

The junk yards are now available in almost every country, state and locality known as the local junk yards. By this fetching for the local junk yards become very easy for every ordinary people whether he /she wants to purchase any automotive parts or want to sell his/ her car in these local junk yards.

Alternators in Junk Yards:-

One of the parts that are really very important for any automobile is the alternator which is also now available in all the local junk yards. This is simply an electromechanical device that converts the mechanical energy into electrical energy in the form of alternating current. These alternators use either the rotating or linear magnetic field for performing its operations. This can also be analogous to the AC electric generator for generating the electricity in the other electric appliances and device.

The alternators are used in the cars for charging the battery of the cars and also to provide power to the electric system when the car is in motion. The strength of the alternator is directly related with the overall performance of the car means stronger the alternator is the more output a car can get. The alternators found in the trucks and passenger vehicles are having the Lundell or claw-pole field construction. This is the field where both the poles (north and south) of the magnet are energized by the same and only one winding and the poles look more like fingers of two hands that are interlocked with each other.
