The aluminum tube is detonated at the end extending out and beyond the copper-wire helix. On the other end a transformer enables the generator to work more efficiently into the electrical load. An explosively pumped flux compression generator ( EPFCG ) is a device used to generate a high-power electromagnetic pulse by compressing magnetic flux ...
The GR-1 uses a clamped quasi-resonant (CQR) step-up inverter described in U.S. Patent 10,811,995, [1] which allows a six-cell 25.2 volt lithium-ion polymer battery to supply up to 1000 watts of power to eight high-voltage electrolytic capacitors in approximately three seconds. [2]
The electromagnetic tensor is the combination of the electric and magnetic fields into a covariant antisymmetric tensor whose entries are B-field quantities. [1] = (/ / / / / /) and the result of raising its indices is = = (/ / / / / /), where E is the electric field, B the magnetic field, and c the speed of light.
The gauss is the unit of magnetic flux density B in the system of Gaussian units and is equal to Mx/cm 2 or g/Bi/s 2, while the oersted is the unit of H-field. One tesla (T) corresponds to 10 4 gauss, and one ampere (A) per metre corresponds to 4π × 10 −3 oersted .
The Gauss gun (often called a Gauss rifle or Gauss cannon) is a device that uses permanent magnets and the physics of the Newton's cradle to accelerate a projectile. Gauss guns are distinct from and predate coil guns , although many works of science fiction (and occasionally educators [ 1 ] ) have confused the two.
According to ISO 764 or its equivalent DIN 8309 (Deutsches Institut für Normung - German Institute for Standardization) a watch must resist exposure to a direct current magnetic field of 4800 A/m. The watch must keep its accuracy to ±30 seconds/day as measured before the test in order to be acknowledged as a magnetic-resistant watch.
At low speeds the heating of the coils dominates the efficiency of the coilgun, giving exceptionally low efficiency. However, as speeds climb, mechanical power grows proportional to the square of the speed, but, correctly switched, the resistive losses are largely unaffected, and thus these resistive losses become much smaller in percentage terms.
The magnetic field (marked B, indicated by red field lines) around wire carrying an electric current (marked I) Compass and wire apparatus showing Ørsted's experiment (video [1]) In electromagnetism , Ørsted's law , also spelled Oersted's law , is the physical law stating that an electric current induces a magnetic field .
