Is this phenomenon explicable with the simple laws of electromagnetism alone?
Pulsars are highly magnetized rotating neutron stars, which means they have a strong magnetic field and are spinning rapidly. As they rotate, their strong magnetic field and fast rotation create a powerful electric field that accelerates charged particles, causing them to emit electromagnetic waves.
The strong magnetic field of a pulsar is a result of its collapsed core. When a massive star runs out of nuclear fuel, it undergoes a supernova explosion and its core collapses. This collapse causes the magnetic field to become highly compressed and intensified, resulting in a pulsar's strong magnetic field.
Pulsar's magnetic poles do not align with their rotational poles. This causes the charged particles accelerated by the strong magnetic field to be ejected from the pulsar's poles rather than from its equator. As these particles travel along the magnetic field lines, they emit electromagnetic waves, resulting in the pulsar's characteristic beams of radiation from its poles.
Pulsar emissions can be detected using radio telescopes. These telescopes are able to detect the pulses of electromagnetic radiation emitted by pulsars as they rotate. The pulses are very precise and can be detected in a regular pattern, making it easy to identify pulsars.
Yes, all pulsars emit electromagnetic waves. However, not all of them are detected by Earth-based telescopes because they may not be aligned in a way that their emissions can be detected from our position. Pulsars that are aligned in a way that their beams of radiation pass by Earth are known as radio pulsars and are the most commonly observed type of pulsar.
