Why there is an induced current in a coil when a bar magnet is thrust into the coil?
photons are trapped in the magnetic field when the photon hits the electron of the copper coil the photon take the spot of the electron , its free to move.Answer2: The induced current is a consequence of the conservation of the magnetic field.AnswerCurrent isn't induced into a coil -it's voltagethat is induced. Any current flows as a consequence of this induced voltage only if there is a load connected to the coil.
Why there is an induced current in a coil when the bar magnet is thurst into the coil?
This is called ELECTROMAGNETIC INDUCTION. The electrons have a magnetic field; the magnetic fields of electron and bar magnet interact. Both the bar magnet and the electrons are "pushed". The electrons are lighter; they move more easily. Moving electrons are called a current.
Why did Nikola Tesla invent the Tesla coil?
Nikola Tesla invented the Tesla coil as part of his research into wireless energy transmission and electricity. He utilized the coil to experiment with high-frequency alternating current power transmission and wireless communication. The coil also played a key role in his demonstrations and experiments showcasing the potential of electricity and wireless technology.
Is the direction of electron beams in a CRT is controlled by electric field?
Yes, the direction of electron beams in a CRT (Cathode Ray Tube) can be controlled by electric fields. The electric fields guide the electrons to different areas of the screen, allowing them to create the desired images or text.
What would happen if the current passing through the coil was too large?
The coil offers some amount of Resistance to the flow of Electric current through the coil. The Resistance of the coil depends on the material used to make the coil and the thickness of the coil wire ( its gauge ) When a current flows through the coil, the voltage drop across the coil and the Power dissipated in the coil both are proportional to the magnitude of current and the coil resistance. Normally the coil is rated to carry certain current and dissipate certain amount of power without causing any damage. If a large magnitude of current flows through the coil beyond its rating , the voltage drop across the coil and the power dissipation in the coil both increase substantially causing over heating of the coil. This can damage the coil and may result in burning of the coil
What best describe and electron microphone?
An electron microphone is a type of microphone that uses a diaphragm to convert sound waves into electrical signals through the movement of a coil or capacitor in a magnetic field. These microphones are known for their durability, high sensitivity, and accuracy in capturing audio signals. They are commonly used in recording studios, live performances, and broadcasting.
Working of moving-coil galvanometer?
A moving coil galvanometer is a type of scanning device used in the transportation and trucking industry. The vehicle is pulled through a fixed scanner while an operator watches a closed circuit television.
What are the advantages of an electron microscope?
it can magnify up to 500,000 times == == == == == Electron microscopes are expensive to build and maintain, but the capital and running costs of confocal light microscope systems now overlaps with those of basic electron microscopes. They are dynamic rather than static in their operation, requiring extremely stable high-voltage supplies, extremely stable currents to each electromagnetic coil/lens, continuously-pumped high- or ultra-high-vacuum systems, and a cooling water supply circulation through the lenses and pumps. As they are very sensitive to vibration and external magnetic fields, microscopes designed to achieve high resolutions must be housed in stable buildings (sometimes underground) with special services such as magnetic field cancelling systems. Some desktop low voltage electron microscopes have TEM capabilities at very low voltages (around 5 kV) without stringent voltage supply, lens coil current, cooling water or vibration isolation requirements and as such are much less expensive to buy and far easier to install and maintain, but do not have the same ultra-high (atomic scale) resolution capabilities as the larger instruments. The samples largely have to be viewed in vacuum, as the molecules that make up air would scatter the electrons. One exception is the environmental scanning electron microscope, which allows hydrated samples to be viewed in a low-pressure (up to 20 Torr/2.7 kPa), wet environment.

How many springs should there be in a mattress to make it a good mattress?
You are talking about the coil count here. Generally speaking, the more coil, the better it is. But today, the coil design and construction plays an important role as well. See the link to bestbedguide.com
What is the role of chowk in tubelight?
tubelight require a high initial voltage to ionise the inert substance present in vapour form inside the discharge tube and that roll is played by the inductance coil(chowk coil )
