The electromagnet uses this principle. An electromagnet can be defined as a magnet which functions on electricity. Unlike a permanent magnet, the strength of an electromagnet can be changed by changing the amount of electric current that flows through it. If the current flow …

PRINCIPLE Microwave oven works by passing non-ionizing microwave radiation, usually at a frequency of 2.45 GHz (a wavelength of 12.24 cm), through the food. Microwave radiation is between common radio and infrared frequencies. Water, fat, and other substances in the food absorb energy from the microwaves in a process called dielectric heating.

An electric Iron is a combination of heat and pressure removes wrinkles. The principle of the electric iron is that when current is passed through a coil, the coil gets red hot and transfers the heat to the base plate of the electric iron through conduction. 8. There are basically two types of electric irons: 1) Automatic 2) Non-Automatic 9.

The working principle is simple; impact and attrition size reduction take place as the ball drops from near the top of a rotating hollow cylindrical shell. The nanostructure size can be varied by varying the number and size of balls, the material used for the balls, the material used for the surface of the cylinder, the rotation speed, and the ...

Figure 1. Iron absorption. Iron enters the stomach from the esophagus. Iron is oxidized to the Fe 3+ state no matter its original form when taken in orally. Gastric acidity as well as solubilizing agents such as ascorbate prevent precipitation of the normally insoluble Fe 3+ .Intestinal mucosal cells in the duodenum and upper jejunum absorb the iron.

We all know that a control system manages or directs the operation of a system in order to provide a specific output. In a closed-loop system, the desired output is achieved by making a comparison between achieved output and provided input. And for this purpose, a part of the output is fed back to the input in order to have the difference in the input and output value.

The GC4410 iron box ensures fast, convenient and powerful ironing; this is because of its light weight and user friendly design to minimize any form of strain when in use. It also. 7. 7 requires relatively low power of about 220-240 v, 50/60 Hz frequency and consumes about 2400 watts of power when being used.

magnesium, and iron salts are not. Thus, when soaps are placed in hard water that contains such ions, an insoluble, curdy solid forms. Most of us have seen these results in the form of a bathtub ring or soap scum floating in bath or wash water. This process removes soap ions from solution, and decreases the cleaning effectiveness of soaps.

The black box Reference Electrode: Defines "0" potential for the cell. Use: Ag/AgCl Working Electrode: Where the redox reaction action occurs Use: glassy carbon, platinum and gold. Counter / Auxiliary Electrode: Needed to complete circuit. Use a Pt wire 8.

Cathodic Protection is an industrial technique for controlling metallic corrosion. Cathodic protection is commonly used on buried and submerged metallic structures like pipelines, underground storage tanks, locks, subsea equipment, offshore floaters, harbours, and ship hulls.

Work the iron from the shoulder to the back. Repeat on the other side. Work from the cuff to the shoulder when ironing sleeves. 2. Iron pants from the waist to the leg. If your pants have pockets, turn them inside out and begin by ironing the pockets. If they do not have pockets, you can proceed to the regular ironing process.

Three Point Starter: Diagram and Working Principle. January 24, 2021. February 24, 2012. by Electrical4U. A 3 point starter is a device that helps in the starting and running of a DC shunt motor or compound wound DC motor (similar to a 4 point starter ). Now the question is why these types of DC motors require the assistance of the starter in ...

Iron making. Recrystallization is a process by which deformed grains are replaced by a new set of undeformed grains that nucleate and grow until the original grains have been entirely consumed. Recrystallization is usually accompanied by a reduction in the strength and hardness of a material and a simultaneous increase in the ductility .
