This document provides an overview of magnetic particle testing (MPT). MPT can detect both manufacturing defects and in-service damage in ferromagnetic materials. The basics involve magnetizing a test specimen, which causes discontinuities to distort the magnetic field and produce indications. Iron particles coated with dye are applied and cluster at these indications. The procedure involves pre-cleaning, magnetizing the specimen, applying particles, and interpreting any visible indications of discontinuities. MPT can be done with dry or wet particles and produces indications of cracks and defects.
Introduction to NDT and Visual Inspection Hareesh K
This presentation will gives you basic idea about Non destructive testing and brief detail about Visual Inspection Technique.This topic is included in UG level Mechanical Engineering Syllabus by all top Indian Universities
NDT-Nondestructive testing is the process of inspecting, testing, or evaluating materials, components or assemblies for discontinuities, or differences in characteristics without destroying the serviceability of the part or system. In other words, when the inspection or test is completed the part can still be used.
This presentation Based on Non Destructive Testing.the Abbreviation is NDT.Dye penetrant Testing (DPT) is the part of NDT .I think my presentation will be helpful for NDT Related person
NON DESTRUCTIVE TESTING TECHNIQUES ARE USEFUL FOR FINDING DEFECTS LIKE CRACKS,POROSITY,FLAWS,BLOWHOLES IN MATERIALS WITHOUT DESTRUCTING COMPONENT. IT IS ALSO USEFUL FOR TAKING DECISIONS RELATED TO QUALITY OF MATERIAL OR PRODUCT. Non destructive testing includes study and testing of components by various methods such as dye penetration test, eddy current test, magnetic particle test, ndt, radiography test, ultrasonic test.

Magnetic particle inspection is an inspection method used to identify defects on the surface of ferromagnetic materials by running a magnetic current through it. It can also be used to detect defects just beneath the surface of materials.
This presentation was developed to provide students in industrial technology programs, such as welding, an introduction to magnetic particle testing. The material by itself is not intended to train individuals to perform NDT functions but rather to acquaint individuals with the NDT equipment and methods that they are likely to encounter in industry. More information has been included than might necessarily be required for a general introduction to the subject as some instructors have requested at least 60 minutes of material.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Lecture 4 of 5 - Basics of Magnetic Particle Testing
Prepared by
Mr.M.Mani Vannan
Assistant Professor
Department of Mechanical Engineering 1
2. Introduction
Magnetic particle inspection can detect both production
discontinuities (seams, laps, grinding cracks and quenching
cracks) and in-service damage (fatigue and overload cracks)
Basics of Magnetic Particle Testing 2
3. Basics of Magnetic Particle Testing
1.A ferromagnetic test specimen is magnetized with a strong
magnetic field created by a magnet or Special equipment.
2.If the specimen has a discontinuity, the discontinuity will
interrupt the magnetic field flowing through the specimen
and a leakage field will occur.
3Basics of Magnetic Particle Testing
4. Basics of Magnetic Particle Testing
3.Finely milled iron particles coated with a dye pigment are
applied to the test specimen.
4.These particles are attracted to leakage fields and will
cluster to form an indication directly over the discontinuity.
5.This indication can be visually detected under proper lighting
conditions.

1. Component pre-cleaning
2. Introduction of magnetic field
3. Application of magnetic media
4. Interpretation of magnetic particle indications
5Basics of Magnetic Particle Testing
6. Pre-cleaning
Contaminants such as oil, grease, or scale may not only
prevent particles from being attracted to leakage fields, they
may also interfere with Interpretation of indications.
6Basics of Magnetic Particle Testing
7. Introduction of the Magnetic Field
The required magnetic field can be introduced into a
component in a number of different ways.
1.Using a permanent magnet or an electromagnet that
contacts the test piece
2. Flowing an electrical current through the specimen
3. Flowing an electrical current through a coil of wire around
the part or through a central conductor running near the part.
7Basics of Magnetic Particle Testing
8. Application of Magnetic Media
(Wet Versus Dry)
1.MPI can be performed using either dry particles, or particles
suspended in a liquid.
2.With the dry method, the particles are lightly dusted on to
the surface. The dry method is more portable.
3.With the wet method, the part is flooded with a
Solution carrying the particles. The wet method is
generally more sensitive since the liquid carrier gives the
magnetic particles additional mobility.
8Basics of Magnetic Particle Testing
9. Dry Magnetic Particles
1.Magnetic particles come in a variety of colors.
2.A color that produces a high level of contrast against the
background should be used.
9Basics of Magnetic Particle Testing
10. Wet Magnetic Particles
1.Wet particles are typically supplied as visible or fluorescent.
2.Visible particles are viewed under normal white light and
fluorescent particles are viewed under black light.
10Basics of Magnetic Particle Testing
11. Interpretation of Indications
1.After applying the magnetic field, indications that form must
interpreted.
2.This process requires that the inspector distinguish
between relevant and non-relevant indications.
