Magnetic field lines in a solenoid

Coils

A wire coil can be used to concentrate magnetic flux in a controlled area. The most common form of coil, known as a solenoid, can be a single loop of wire or multiple turns in series. The diagram on the left represents the magnetic field in a typical solenoid.

By winding multiple turns in the same direction its possible to increase the total magnetic field strength. A typical solenoid posses a property known as inductance which creates a resistance to the change of flow of current in the wire.

Helmholtz Coils

This type of coil is used to generate a uniform magnetic field. Two coils are held parallel to each other at a distance less than their diameter . The field between the coils should be quite uniform, providing the strength of the overall field is high enough.

Helmholtz coils are commonly used for scientific tests which require controlled field conditions. They can be used for canceling the earths magnetic field or for testing the effectiveness of magnetic shielding for example.

They are also useful for measuring the magnetic properties of materials.
Nikola Tesla patent of a Bifilar Coil

Bifilar Coils (with opposing windings)

This type of coil, when powered does not create an external magnetic field. Its construction is similar to that of a normal solenoid, but each turn of the coil carries the current in opposite directions. The opposing currents create an overall canceling effect, thus no major external field is produced. A bifilar coil will produce almost no inductance to a changing, or AC current. This makes them useful for creating non-inductive wire wound resistors.

Scalar theory suggests that this type of coil produces 'Scalar Waves', but the standard model of physics does not accept scalar waves as a valid theory. Bifilar coils are often mentioned along side so called Over unity, or free energy devices.

This is because the vacuum fluctuations, or 'Zero Point Energy' are like canceled vibrations with a massive energy density, and are seen as scalar waves by some. Standard scientific theory tells us that the entropy (disorder) of a closed system always increases and therefore no useful energy could be extracted from the vacuum.
The image above show a patent by Nikola Tesla for a type of bifilar coil. In this configuration the two wires are wound the same way and then connected in series so that the current flows in the same direction. This allows the magnetic field to combine to produce a larger overall field.

XYZ Coils

These are simply solenoids, or Helmholtz coils arranged to point in all three dimensions. They are also used for scientific tests or experiments involving controlled field conditions. Some theoretical teleportation experiments mention the use of XYZ coils for creating some kind of 'fourth dimensional' field When this field is coupled to an object and then driven at some fundamental resonant frequency, the object could be made to move in the fourth dimension. An observer would see the object disappear and then re appear in a different location.

Penning Trap - Plasma Containment

Penning Trap used for containing plasma by magnetic fieldsA Penning trap is a set of electromagnets or coils that will create a controlled non-uniform magnetic field. The diagram on the left shows how the magnetic field is slightly less intense in the centre of the trap. This 'bubble' in the field lines is where a non neutral plasma can be contained. A non neutral plasma is simply a plasma that has an overall positive or negative charge, such as a collection of electrons. A charged 'particle' such as an electron would require an accelerating force to move it across the magnetic field lines. Without this external force the electrons in a penning trap will tend to spiral back and forth within the area of weakest field. The converging field lines at each end act like a 'magnetic mirror' allowing the plasma to remain contained .

Which electromagnet gives off the most force

It would depend on how you were trying to apply the force. The calculations can get a little technical because there are several factors to consider.
If you are just wanting to make an electromagnet, the best way is a simple solenoid wound on a ferrous (iron) core. Placing iron in the core of a solenoid will increase the field strength. Different materials will also help or hinder the flux. You could try winding a solenoid on a hollow plastic tube, then inserting different materials into the tube to see how they affect things.

The magnetic flux produced by the coil is proportional to the current, the number of turns, and the density of the turns. Increasing any of these will increase the field strength.
If you add significantly more turns the resistance of the coil will be larger. This would mean that for the same battery or voltage, the current would be less (see ohms law).
To overcome the increase in resistance you could use thicker wire, but then this will obviously mean that the number of turns you can fit in a given space is reduced. There is always a compromise somewhere.
Another way to increase the current without increasing the voltage is to cool the coil down. you can see how temperature effects resistance of a coil in this experiment.

Please prevent explosion of the planet.
First study the Tachyonator for example.
See http://www.iris.edu for current earth quakes.
The shifting of the tectonic plates, fault lines and 23.45 degree inclination where possibly caused by time travelers that tried to change our past that caused multiple time-lines that stress and endanger our reality, our time-line and our planet.
I hope the Terrawatts and knowledge is used to stabilizer our planet in stead of to create the man made earth quakes (see http://weatherwars.info for seismograms that prove the earth quakes where man made and information about scalar and the Genius Tesla).
In 2025 the world will run out of cancer oil at the present rate of consumption so the electrolitic capacitor, the http://waterpoweredcar.com car and planes flying on hydrogen and other forms of free energy and wireless energy will be used.
To people (ab)using the above information at the moment: please use a frequency generator because one of these coils amplifies the energy with a factor 250000 Volt, can let our planet explode when handled improperly and when used in combination with 220 or 110 Volt would cause a black out, fire and cancer in all people exposed to the field.
Usually frequencies like 15 Hertz are used with a so called succor punch which has a mobius coil wrapped quartz crystal. My experience is that these do not block their scalar surveillance satellite attacks so please let me know if you know a way to block their scalar wave attacks.
These scalar waves pass through all types of matter and do not loose their power when travelling so it is very important only healing frequencies are used in combination with this active succor punch instrument.
See http://doctorno.wordpress.com for more information and if you want to mail me to exchange information about scalar and zero point energy generators. My goal is blocking their scalar attacks.
Safety first.

Can you give me a link to the write up on this not just some random links and a world ends lecture.
