The magnetic fields cause pulsars. And they have along with cosmic radiation connection with Earthquakes.

Pulsar doesn't necessarily mean neutron star. Also, white dwarfs can form pulsars. The nova- and supernova remnants are things. that form the most powerful reactions in the universe. The pulsar is forming when the magnetic field travels to the poles of the white dwarf and neutron star. Also, black holes are pulsars. They are sending their radiation mainly in X- and gamma-ray areas. The energy level of those pulsars is far higher than in neutron stars and white dwarfs. Fusion happens in both poles of the star fossil which is the remnant of the star that used its energy. 

The fusion that forms a pulsar happens outside the star remnant's shell. And that makes it so interesting for fusion research. 

When those fusion reactions are burning. They send energy to star remnants. That energy impacts from the center of the white dwarf and neutron star. That energy causes quakes in the shell of those cosmic fossils. And that resonance forms gravitational waves. The difference between fusion reactions in cosmic fossils and regular stars is that the fusion in cosmic fossils happens outside its shell. In regular stars, the fusion happens in the star's nucleus. 

The requirement for forming the pulsar is that the magnetic field is strong enough. That it can drive those particles together, causing fusion. Particles that travel to the white dwarf's or neutron star's poles have the same polarity. Ions travel to the negative pole and anions travel to the positive pole. Those particles repel each other. And that's why the magnetic field must be strong enough that those particles can impact each other. 

Fusion reseach and pulsars. 

So energy impulses of pulsar form because of fusion reaction. That reaction forms when a white dwarf or neutron star pulls ions and anions against it. And then the magnetic field acts like a particle accelerator. Sometimes is introduced that the magnetized iron ball can form or assist a fusion reaction. 

In that case, the magnetic field that traps ions and anions is made by using iron balls. In the wildest models, the opposite poles of highly magnetized iron balls would transfer close to each other. Then ions and anions will spray against those iron balls that transport them to their magnetic poles. 

When those opposite poles are against each other. Those ions and anions that are packed to opposite poles will melt together. That kind of fusion system requires an extremely powerful magnetic field. And it's hard to make this reactor produce more energy than it uses. 

The heavily magnetized iron ball will transport anions and ions to its poles. Then ion cannon shoots ions against anions and oppositely if the target is the anion cloud at the other pole. In that case, the iron ball anchors the anions and ions to a position where particle accelerators (ion cannons) can shoot particles with opposite poles to those particles and that could make ion fusion possible. 

Scientists linked cosmic radiation with earthquakes. 

When cosmic radiation hits Earth it transports energy to material. That happens straight or indirectly, through Earth's magnetic field. Especially materials like iron and heavy isotopes. Changes in temperature of the temperature of magma cause that magma expands and shrinks. That affects Earth's shell. 

Things like radio waves always act similarly. They are warming up material where they impact. If short-term radio impulses like FRB hit the magma or Earth's core that causes an effect where iron atoms will take energy to their structures. And when the energy level decreases those atoms release their extra energy to magma. 

The energy impulses that cause things like whirls in magma must not affect straight with Earth. The effect can also be indirect. When cosmic radiation hits Earth magnetic field raises the plasma's energy level in that field. That energy travels to the Earth's core, where it reflects the shell. 

When cosmic radiation hits things like radioactive isotopes. It raises the temperature and increases the speed of the radioactive divide. The radiowaves that impact Earth's magnetic field interact with the plasma. That surrounds Earth. The energy that transfers to plasma in Van Allen belts causes electromagnetic resonance. Plasma sends energy impulses to the Earth's nucleus. And then that energy reflects from the Earth's core. 

The interaction between Earth and cosmic radiation is not very easy to model. All things like radioactive divide, and volcanic activity. local and global temperature, the energy level of plasma around the Earth. And many other things cause interactions that can cause dramatic things on Earth.
