Humans are able to detect pulsars when one of their beams crosses paths with the Earth. When this happens, we are able to detect the resulting electromagnetic radiation in the radar spectrum.
The size of an average pulsar is about 20 kilometers in diameter. Pulsars are highly magnetized rotating neutron stars that emit beams of electromagnetic radiation, and their small size makes them incredibly dense objects.
No, a pulsar has not been discovered near the sun. Pulsars are neutron stars that emit beams of radiation that can be detected by astronomers, but they are typically found in distant regions of our galaxy.
Pulsar stars get their name from the pulses of radiation they emit as they rapidly rotate. These pulses are detected as regular intervals of electromagnetic radiation, such as radio waves, X-rays, and gamma rays. The word "pulsar" is a combination of "pulsating" and "star."
The closest known pulsar to Earth is the PSR J0108-1431, which is located about 424 light-years away in the constellation Cetus. Pulsars are highly magnetized rotating neutron stars that emit beams of electromagnetic radiation.
The nearest known pulsar to Earth is PSR B1821-24, located approximately 6,500 light-years away in the constellation of Sagittarius. Pulsars are highly magnetized, rotating neutron stars that emit beams of electromagnetic radiation. While there may be closer pulsars yet to be discovered, PSR B1821-24 currently holds the title for the closest confirmed pulsar.
it is a (n) pulsar
yes, some do.
A Pulsar is highly magnetised, rotating neutron star that emits a beam of electromagnetic radiation.
That would be called a "pulsar". See related question
It's called a pulsar. However - ALL young neutron stars emit the said beam. It's only if that beam is detectable on Earth is it called a pulsar. So a Neutron Star and a Pulsar are the same thing. See related questions. but then again they are different.
Pulsars are highly magnetized, rotating neutron stars that emit a beam of electromagnetic radiation
A Pulsar is a highly magnetized, rotating neutron star that emit a beam of electromagnetic radiation.This can only be seen if the "beam" is pointing towards Earth.
Because they both emit regular pulses of electromagnetic radiation
the existence of released energy
If a neutron star's rotational period is fast enough to produce jets (A pulsar), said jets will emit radio waves, with faster periods emitting higher frequency radiation as well as the jets themselves emitting synchrotron radiation. Also, unless the neutron star were 0K, it will emit thermal radiation However, as far as a neutron star that isn't a pulsar, nobody knows if they emit anything but thermal radiation.
How do you proof of the existence of back emf ?
No. Any person trained in logic will tell you that 'you cannot prove a negative'. If you want to disprove the existence of fairies you first attempt to try and prove their existence. And the best you can do is to fail to prove it. The option to prove it always exists.
