why neutron star have tremendous magnetic field even they contain only neutron particle?

Question

Dear Sir,
My question is something like this.
neutron stars are made of neutron particles only. neutron particles are electrically neutral. thats why motion of neutron particle can not produce electric current and thats and thats why no magnetic field. but as we know netron stars have stronge magnetic field. where this magnetic field come from? what is the producer of this magnetic field? what is the phenomena that occure and make stronge magnetic field.
regards,
LG

Answer 1

It indicates that the neutrons (which are built from quarks) present in the neutron stars (spinning at high pace) due to the high pace and due to the interactions between the quarks may acquire such a state so that the quarks instantaneously behave in a way which indicates that as if they were forming and protons and electrons. But actually they compose neutrons. ( I know it's difficult to try and explain it.)

Look at this analogy when light propagates it behaves like waves but when it interacts with matter it behaves like particles(photons).

Similarly the quarks constituting the neutrons (when they are present in a pulsar behave as though they were constituents of protons and electrons.). But if you were to some how 'interact' with the constituents of the neutron star or rather snatch them away (somehow!). They'll behave like 'pure' neutrons... that is as you said they'll be neutral... and wouldn't exhibit magnetism.

Answer 2

A typical neutron star is the size of a small city, only 10 Kilometers in diameter but it may have the mass of as many as three suns. It is quite dense. One spoonful of neutron star material on Earth would weigh as much as all the cars on Earth put together.

Some neutron stars spin very rapidly and have very strong magnetic fields. If the magnetic poles are not lined up with the star's rotation axis then the magnetic field spins around very fast. Charged particles can get caught up in the magnetic fields and beem away radiation like a lighthouse lamp. This type of neutron star is called a pulsar. Pulsars are detected by their rapidly repeating radio signals beemed at Earth from those charged particles trapped in the magnetic field.

Neutron Stars are the end point of a massive star's life. When a really massive star runs out of nuclear fuel in its core the core begins to collapse under gravity. When the core collapses the entire star collapses. The surface of the star falls down until it hits the now incredibly dense core. It then bounces off the core and blows apart in a supernova. All that remains is the collapsed core, a Neutron Star or sometimes a Black Hole, if the star was really massive.

Answer 3

A supernova explosion does not always completely shatter the star. Often a tiny core is left at the centre. But it is not ordinary matter. It is completely made up of tiny atomic particles called neutrons and we call it a neutron star.
Because it is made up of solid neutrons, it is incredibly dense. It contains the mass of several suns crushed into a ball perhaps only 25km (15 miles) across. Each teaspoonful of its matter weigh millions and millions of tonnes. The collapsing matter not only concentrates the matter but also its magnetism. hence they have a tremendous magnetic field.

Answer 4

Neutron stars spin very very VERY fast. The magnetic field is produced by the spin itself much the same way as a generator produces electricity using a spinning coil.

Answer 5

None of your alternatives is truly suitable suited, however pulsar is the closest. while a neutron famous guy or woman has an exceedingly sturdy magnetic field, they are talked approximately as "magnetars" to tell apart them from uncomplicated neutron stars. All stars rotate - neutron stars that rotate such that their magnetic poles (and as a result the jets of radio waves) sweep for the duration of our view are talked approximately as pulsars.

Answer 6

The Nuetron itself is very dense without electrons to give the star volume you have a very strong gravitation and with the fast rotation of the star you achieve a polar alignment and thus magnetic field

Answer 7

Neutrons are composed of a proton and an electorn, so there will be currents within the star, even though the overall charge is neutral.

Answer 8

It may have to do with the sub-atomic particles reaction to the environment.

Or it could have to do with the immense mass affecting the fields around it.

Not quite sure though, but I remember something like that.
