The reason is that, when voltage or potential difference is applied across an inductor, the electric current flowing through an inductor produces a magnetic field. This magnetic field again creates an induced electric current in the inductor but of opposite polarity, according’s to Lenz’s law....
Earth's magnetic field then redirects the particles toward the north and south poles. The electrically charged particles then enter Earth's atmosphere, exciting gas atoms and molecules and generating auroras. The process is similar to how neon lights work: When the molecules and atoms get "...
magnets. The reading of the flux meter is related to the position of the sample in the measuring coil. The calibration of the test coil requires a constant current to test the size of the magnetic field in a zero magnetic field environment, and then the constant of the test coil is ...
Once a head arrives at a certain location on a platter, an electromagnet produces a magnetic field, which aligns data-carrying domains in the underlying track. Each domain can be aligned in one of two possible directions — 1 or 0. As these alignments change, they form patterns that ...
A time-varying electric current produces electromagnetic waves, which are used in telecommunications to broadcast data. AC vs DC Current Based on the flow of charge, the electric current is classified into two types, i.e., alternating current (AC) and direct current (DC). AC Current The flow...
optical cavity. This cavity amplifies a laser that is exposed to an intense magnetic field produced by 12 superconducting magnets as it travels down the tunnel. It's thought that such a powerful magnetic field might turn a photon into an axion, thus revealing the hypothetical particle to be ...
Beijing has placed strict restriction on the number of newly purchased car in the city and the policy bas sparked heated discussion. Some people support the policy, saying it,s a powerful method to cope with the severe traffic congestion in the capital. With cars increasing drastically in the ...
Loaded the question to trick the witness. Force To rape. Load To raise the power demand in (an electrical circuit), as by adding resistance. Force To induce change in (a complex system) by changing one of its parameters Greenhouse gases that force the earth's climate. Load To increase (...
Now, let the input voltage E, is applied across the brushes.Electric currentwhich flows through the rotor armature via brushes, in presence of themagnetic field, produces a torque Tg. Due to this torque Tgthe dc motor armature rotates. ...
