- In ferromagnetic materials like iron, magnetic domains align with an applied magnetic field, causing domains favorably oriented to grow at the expense of unfavorably oriented domains.
- Materials respond differently to magnetic fields based on their properties, including diamagnetism, paramagnetism, ferromagnetism, antiferromagnetism, and ferrimagnetism.
- Hysteresis curves relate the magnetic flux density B and magnetic field strength H for ferromagnetic materials, exhibiting properties like saturation magnetization, remanence, and coercivity.

ION THRUSTERS (an application of plasma physics) pptBhushith Kumar
Plasma has lured the attention of physicists towards itself for quite some time now. 99% of the universe is made up of plasma. It is the purest form of raw and intense energy which possesses all the types of matter known to mankind. Scientists have come up with various theories and technologies to harness this versatile source of energy. The “plasma propulsion” is a technology which harnesses plasma to achieve vehicular propulsion, mostly spacecrafts. This technology is gaining importance due to the depletion of conventional sources of energy such as fossil fuels which are used to fuel vehicles for transportation. This paper showcases the ideology of plasma and its types. Further, this article also deals with the types of plasma propulsion systems, their architecture, working, pros and cons, and the types of propellants used in ion thrusters. This paper also houses a brief description of various missions which have incorporated ion thrusters. And towards the fag end of this article, a vision of “terrestrial transportation” has also been idealized followed by the list of references.

Inverter is a device which convert a DC input supply voltage into symmetric AC voltage of desired magnitude and frequency at the output side. It is also know as DC-AC converter.
Ideal and practical inverter have sinusoidal and no-sinusoidal waveforms at output respectively.
If the input dc is a voltage source, the inverter is called a Voltage Source Inverter (VSI). One can similarly think of a Current Source Inverter (CSI), where the input to the circuit is a current source. The VSI circuit has direct control over ‘output (ac) voltage’ whereas the CSI directly controls ‘output (ac) current.

The commutator and brush arrangement is used to convert bidirectional internal current to unidirectional external current or vice versa.
The current flows through the brush mounted on the commutator.
The brushes are located at magnetic neutral axis which is midway between two adjacent poles.
Types of commutation:
Resistance commutation
Retarded commutation
Accelerated commutation
Sinusoidal commutation

Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.

• A magnetic field can be produced by:
--putting a current through a coil.
• Magnetic induction:
--occurs when a material is subjected to a magnetic field.
--is a change in magnetic moment from electrons.
• Types of material response to a field are:
--ferri- or ferro-magnetic (large magnetic induction)
--paramagnetic (poor magnetic induction)
--diamagnetic (opposing magnetic moment)
• Hard magnets: large coercivity.
• Soft magnets: small coercivity.
• Magnetic storage media:
--particulate g-Fe2O3 in polymeric film (tape or floppy)
--thin film CoPtCr or CoCrTa on glass disk (hard drive)
