the action of a solenoid coil. A contactor is used to control an electric load in a control system. Contactors make or break a set of contacts that controls the voltage applied to some load in cooling systems. A contactor consists of a coil that opens and closes a set of contacts due to the magnetic attraction created by the coil when it is energized. Magnetic starters are also used to start and stop large loads in cooling systems. The major difference between magnetic starters and contactors

service and important to the investigation of fire origin and cause. Fire and arson investigators need to be aware of search and seizure laws. There have been several court decisions and laws created regarding proper search and seizure procedures for fire and arson investigators. Research into these laws and court rulings will help fire and arson investigators understand what type of search warrant is required‚ if search warrants can be obtained‚ and who can obtain a search warrant.

repellents are essentially required these days. Mosquito coils are one of the cheapest and effective way of avoiding them‚ but this coils are made up of chemicals which can harm our health. So we thought about making a substitute mosquito coil that is not harmful to our health and that is the Anstor katol a natural and environmental friendly coil. Introduction Background of the Study: We chose this project because a mosquito coil made up from natural mosquito repelling plants will remove

Mud Flat Field and Marmaduke Spring are located in the Owyhee Mountains‚ in the west central portion of Owyhee County‚ south of South Mountain and north of Juniper Mountain. The Mud Flat Field is approximately two miles long from North to South. The south end of the Mud Flat Field borders the Mud Flat road. Over this road one can travel to Jordan Valley‚ Oregon‚ from Grandview‚ Idaho. From the

Magnetic particle inspection (MPI) - Is a non-destructive testing (NDT) process for detecting surface and slightly subsurface discontinuities in ferroelectric materials such as iron‚ nickel‚ cobalt‚ and some of their alloys. The process puts a magnetic field into the part. The piece can be magnetized by direct or indirect magnetization. Direct magnetization occurs when the electric current is passed through the test object and a magnetic field is formed in the material. Indirect magnetization occurs

generation the physical means such as gravity‚ vacuum or magnetic field is used for stabilization of the free flowing dry moulding materials. The development of unbounded casting process improves flexibility and enhances mould ability. The concept of unbounded casting is to change the kind of binder or to avoid substantial binder. Magnetic moulding is a type of unbounded moulding process in which a dry and free flowing magnetic steel shots or granules are used as mould materials

Permanent Magnet Moving Coil: Principle of Working When a current carrying conductor is placed in a magnetic field‚ it experiences a force and tends to move in the direction as per Fleming’s left hand rule. Fleming left hand rule: If the first and the second finger and the thumb of the left hand are held so that they are at right angle to each other‚ then the thumb shows the direction of the force on the conductor‚ the first finger points towards the direction of the magnetic field and the second finger
