If a current loop does not radiate EM waves, then why does a pulsar? If the charge is evenly spread through the pulsar and its rotation creates the B field. I Don't understand why it radiates?
A pulsar is a highly magnetized, rotating neutron star that emits beams of electromagnetic radiation. It is formed when a massive star undergoes a supernova explosion and its core collapses.
A pulsar emits radiation due to its intense magnetic field and rapid rotation. This causes particles to accelerate and emit beams of radio waves, X-rays, and gamma rays in a lighthouse-like fashion.
The radiation emitted by a pulsar is highly energetic, but it is not harmful to humans. This is because pulsars are usually located far away from Earth and the radiation is directed in specific directions, making it unlikely to hit our planet.
Yes, pulsars can be used for navigation in space. They have a very precise and stable rotation rate, making them useful as a cosmic clock for spacecraft and satellites.
Scientists study pulsars using various methods, including radio telescopes, X-ray telescopes, and gamma-ray telescopes. These telescopes capture the radiation emitted by pulsars and provide valuable data for understanding their properties and behavior.
