A changing magnetic field generates an electric field and alternating currents are accompanied (or caused) by alternating voltages.

Compare alternating current with direct current?
Alternating current changes direction on a set frequency such as 50 Hz, 60 Hz or 400 Hz. Direct current always flows in one direction.
Why high frequency signal is more affected by noise compare to low frquency signal?
AS FREQUENCY INCREASE THE BANDWIDTH INCREASE. AS WE KNOW NOISE HAVE LARGER BANDWIDTH. SO ITS AFFECT HIGH FREQUENCY SIGNAL. BUT LOW FREQUENCY SIGNAL HAVE LOW BANDWIDTH SO IT IS LESS AFFECTED BY NOISE. ALSO WE KNOW QUALITY FACTOR= CUTOFF FREQUENCY / BANDWIDTH. SO AS FREQUENCY INCREASE B.W. INCREASE SO QUALITY DEGRADE. CUTOFF FREQUNCY AND THE TERM FREQUENCY (USED HERE) IS DIFFERENT. CUTTOFF FREQUNCY IS USED IN FILTER. PRABIR KUMAR SETHY prabirsethy.05@gmail.com
How does the peak value of an alternating voltage compare to its quoted value?
The quoted value is usually RMS value, i.e it is lesser than the peak value of the voltage, therefore the peak value is sqrt(2) times the quoted value. (it is a sine wave)
How to compare two array list when one array list always fluctuate rows?
I am creating one array list and attempting to equals to another array list, the reader through CSV file. CSV row is not in the same order, changing everything when downloading. I tried with equals and compare to but both fail due to row fluctuations. How do I compare? Apart from row number, everything is the same .

What happens to the direction of the magnet field about a straight section of wire when the direction of the current is reversed?
In that case, the magnetic field caused by the current would also be reversed. As for the wire itself, it would feel a force in the opposite direction, due to the interaction of the magnetic fields.
Compare alternating current with direct current?
Alternating current changes direction on a set frequency such as 50 Hz, 60 Hz or 400 Hz. Direct current always flows in one direction.
Are electromagnetic waves stronger than regular magnetic waves?
Electromagnetic waves are a combination of electric and magnetic fields that propagate through space. They carry energy and can vary in strength depending on factors like frequency and amplitude. On the other hand, "regular" magnetic waves may refer to static magnetic fields which do not propagate like waves. It is not accurate to compare the strength of electromagnetic waves with regular magnetic waves as they represent different phenomena.
How does the frequency of the waves compare in the two diagrams?
use an ruler
What is a graph used to compare categories of data?
frequency table
What are the applications of deflection magnetometer?
To compare the magnetic moments of two different bar magnets. To check the earth magetic moment. To verify inverse square law . Compare earth's magnetic induction . determine the horizontal component of the earth's magnetic induction .
How do you compare magnetic moments of two magnets using deflection magnetometer?
To compare the magnetic moments of two magnets using a deflection magnetometer, you would place one magnet at a known distance from the magnetometer and measure the angle of deflection caused by its magnetic field. Then, you would repeat the process with the second magnet at the same distance and compare the angles of deflection. The magnetic moment of the magnets can be compared by the ratio of the sine of the angles to the distance and the Earth's magnetic field strength.
Which wavelength possesses the lowest frequency?
Provided you compare waves that all have the same speed, the longest wave has the lowest frequency.
How do infrared waves compare with gamma rays?
Much lower frequency.
What are advantages and disadvantages of cumulative frequency?
advantages: -very informative when examining how values are changing within the data set. -shows the running total of frequencies from the lowest interval up. disadvantages: -difficult to compare the frequencies between each data group. by Mr. Hsia
How does the wavelength of light compare to it's frequency?
The wavelength of light is inversely proportional to its frequency. This means that light with a shorter wavelength will have a higher frequency, and light with a longer wavelength will have a lower frequency. In other words, as the wavelength decreases, the frequency increases.
How does the incident frequency compare to the reflected frequency?
Incident frequency is the original frequency of an incoming wave, while reflected frequency is the frequency of the wave that is bounced back after hitting a boundary. In general, the incident frequency is the same as the reflected frequency because the wave retains its original frequency upon reflection, assuming no frequency changes occur due to the medium.
Compare 116kHz and 512 Hz?
The first has a frequency that is 226.5625 times at high.
