What is claimed is: 1. An apparatus for welding or joining of workpieces comprising: a control module capable of generating energy sufficient for welding or joining workpieces by a magnetic field; an induction coil electrically coupled to said control module for generating said magnetic field, wherein said induction coil is selectively separable along at least one portion thereby forming a gap in said induction coil so that the workpieces can pass through said gap and be circumscribed by said induction coil, wherein said induction coil is hand-held; and a handle operably connected to said induction coil, wherein said handle is electrically insulated from said induction coil. 2. The apparatus of claim 1, wherein said handle is operably connected to said induction coil for selectively forming said gap in said induction coil. 3. The apparatus of claim 1, wherein said induction coil has a locking mechanism that selectively locks said induction coil in a closed position. 4. The apparatus of claim 1, wherein said at least one portion can be only partially separated from said induction coil such that said induction coil is a unitary device. 5. The apparatus of claim 1, wherein said control module has an adjuster that selectively controls the amount of energy supplied to said induction coil. 6. An apparatus for welding or joining of workpieces comprising: a control module capable of generating energy sufficient for welding or joining the workpieces by a magnetic field; a hand-held induction coil electrically coupled to said control module for generating said magnetic field, wherein said hand-held induction coil is selectively separable along at least one separation line so that the workpieces can pass through said at least one separation line and be circumscribed by said hand-held induction coil; and a handle operably connected to said hand-held induction coil, wherein said handle is electrically insulated from said hand-held induction coil. 7. The apparatus of claim 6 wherein said handle is operably connected to said hand-held induction coil for selectively separating said hand-held induction coil along said at least one separation line. 8. The apparatus of claim 7, wherein said hand-held induction coil has a locking mechanism that selectively locks said hand-held induction coil along said at least one separation line. 9. The apparatus of claim 8, wherein said handle has a locking actuator operably connected to said locking mechanism for selectively locking said hand-held induction coil along said at least one separation line. 10. The apparatus of claim 6, wherein said hand-held induction coil is a unitary device. 11. The apparatus of claim 6, wherein said control module has an adjuster that selectively controls the amount of energy supplied to said hand-held induction coil. 12. The apparatus of claim 11, wherein said control module indicates a plurality of types of material for the workpieces, and wherein said adjuster can be adjusted to one of said plurality of types of material for generating energy sufficient for welding or joining of said one of said plurality of types of material. 13. The apparatus of claim 6, wherein said handle has a trigger that allows selective generating of said magnetic field in said hand-held induction coil. 14. A method of magnetically welding or joining workpieces comprising: circumscribing the workpieces with an induction coil by separating said induction coil thereby forming a gap, passing the workpieces through said gap into an inner volume of said induction coil and closing said induction coil thereby eliminating said gap; generating energy sufficient for welding or joining workpieces by a magnetic field; and supplying said energy to said induction coil to generate said magnetic field in said inner volume, wherein circumscribing workpieces with said induction coil comprises manipulating said induction coil via a handle operably connected to said induction coil and electrically insulated from said induction coil. 15. The method of claim 14, wherein said handle is operably connected to said induction coil for selectively forming said gap in said induction coil. 16. The method of claim 14, wherein the step of supplying said energy to said induction coil to generate said magnetic field in said inner volume is actuated by a trigger operably connected to said handle. 17. The method of claim 14, further comprising: providing a spacing between the workpieces thereby allowing the magnetic field to accelerate the workpieces to a sufficient velocity for welding or joining. 18. The method of claim 17, wherein the spacing is provided via one or more spacers that are separate from the workpieces. 19. The method of claim 17, wherein the spacing is provided via one or more spacers that are integrally formed with one or more of the workpieces. 20. The method of claim 17, wherein the spacing provided between the workpieces and the energy generated causes a substantially complete metallurgical bond between the workpieces.
