I understand gravity is helping keep the sun together, but not only
does it require lots of mass to be effective. Gravity only will not be
able to stop the jets of ionised gas that will be able to escape the
surface of the sun very easily.

What ionized jets are those? Fusion is taking place at
the core where the conditions are right (pressure,
temperature, density). Heat moves outwards largely
by convection and radiation. Convection cell flow
rates are less than escape velocity which is over
600 km/sec.

Particles with velocities that exceed escape velocity
will be lost, sure. We call this the solar wind.
Large coronal mass ejections are thought to be due
to magnetic field effects (reconnections of force
lines), rather than tamed by them.



A heavy stable atom is the only way of generating and maintaining an
effective magnetic field in the right place and right direction.

Prove it or cite references.



The heat energy produced by the fusion process itself will also help
in generating the protection field.

You've overdosed on Startrek technobabble.



A molten iron core will not only generate internal magnetic field
(force shield), it will also attract energy plasma back to the centre
of the core.

Again, prove it or provide references.



If you wish to control the field, then stick another external field on
the outside to control the internal field, but it will not be able to
stop internal reactions from escaping.

Utter codswallop.

Please don't knock Star trek, it has been very inspiring in enabling
us to imagine what we can achieve when we put our hearts in it. It has
motivated a great many new developments in today's technological
society. I am well aware of the dodgy science behind its motivation,
so please can we do try to have an open mind.

Lets start from basic physics. The argument is that gravity is the
only force required produce and maintain fusion successfully, that is
a red herring. Gravity is only effective with large masses greater
distances not on the atomic scale. Its influence is negligible at
microscopic scale.

A power station, starts by producing heat energy, converts this heat
into mechanical energy and eventually with a lot of wastage in the
system converts it into electricity using magnetic fields.

The sun does exactly the same process. In the core, it generates heat
energy by fusion. This energy is carried away from the core by
convection currents (600 km/sec) translating it into mechanical
energy. As convection currents always move in unison, and must
contain plasma (super heated matter). They are electrically charged,
and just what is needed to produce a magnetic pressure bubble on the
surface of the sun. The pressure bubble has to encompassing the whole
of the sun in order to generate the right conditions for fusion to
take place in the core. It fail when sun spots caused, the magnetic
attraction to towards to centre of the sun is reversed and so jets of
charged plasma escapes the magnetic pressure bubble.

Please goggle it or use wikipedia to find out what is magnetic
pressure bubble, there are many references to it.

The most important aspect of fusion processes a magnetic pressure
bubble. It can be maintained using ordinary heat by first converting
the heat from the core into convection currents of super heated
plasma. Then using electrically charged plasma to generate a magnetic
pressure bubble on the border, just by interacting with an existing
magnetic field to strengthen it.

Generation of magnetic fields is generated using basic corkscrew of
eletromagnetism method.

The conditions for fusion is provided by the pressure generated from
the external magnetic bubble, which keeps everything pressurised.
Convection currents moving to the surface translate heat energy into
mechanical energy and are used to power the magnetic pressure bubble.
