Essays on Electromagnetism

The optical microscope has been a standard tool in life science as well as material science for more than one and a half centuries now. The optical microscope widely use in the field of cell biology, microbiology, biotechnology, pharmacology, forensic and medical diagnosis especially when dealing with tissue fragments. It is a type of microscope…

In isolation applications where one needs to pass signals in presence of transient or continuous high voltages, reject extreme noise, and break ground loops, optical (optocouplers) and magnetic (pulse transformers) coupling isolation are often used. However pulse transformers are much more difficult to design with relative to optocouplers. When dealing with pulse transformers, the load…

 Describe what is necessary for a substance to be a conductor Of electricity. In order for a substance to be a good conductor of electricity, there must be charged particles in the substance, ions or electrons. These particles must be free to move within the substance. Form a hypothesis as to whether distilled water is…

Photovoltaic cells are solid state devices that convert light directly into electricity. Photovoltaic literally means “light electricity.” These devices can be commonly found providing power for small scale devices such as calculators, watches, and small radios. However, they are not limited to small scale systems. They are also used to power satellites, communications equipment, houses…

Secondarily, its thickness allows for wear over the life of the clutch. However, that wear results from a fundamental drawback of diabetics design. Since the armature is thick and massive, it has a high inertia, and all of its originally stationary mass must be “spun up” to match the rapidly rotating pulley and friction disk…

Magnetic particle testingNon destructive metal testing Magnetic particle testing involves a non destructive method of testing to detect imperfections on top of the metal or below its surface. This is usually an easy and very reliable means of detecting and locating of faults such as cracks on metal’s surface.The procedure; a flux is ran through the…

Rajasthan Electronics & Instruments Ltd. was founded to aid in the upliftment of the rural masses by enpowering them, making them self-reliant and upgrading their living conditions by taking electronics to the villages. Rajasthan Electronics & Instruments Ltd. (REIL) has a prominent place amongst the electronics industry of Rajasthan. The company is a joint venture…

Introduction This lab was completed to investigate and map the magnetic field pattern of a single straight conductor by comparing it with the earth’s magnetic field. Quantitatively, the purpose of this lab was to determine the horizontal component of the earth’s magnetic field. Magnetic field and electric currents are naturally closely related because anytime a…

INTRODUCTION This is one of the version of spy robot which we designed in this academic period. Intelligent spy robot project has been designed for the spying purpose . it is radio controlled and can be operated at a radial distance of 50 yards. Many time our army jawan need to venture into the enemy…

An electric generator is fundamentally an electric motor working backwards. An electric motor converts electrical energy into mechanical energy. and an electric generator converts mechanical energy into electrical energy. An electric generator looks about indistinguishable to an electric motor. Each consists of a cringle that is able to revolve in a magnetic field. The electric…
