Inductance Of A Aluminum Sheet

The self inductance of a straight wire may only be defined as only a partial inductance and so cannot be measured directly because of the absence of a return path.

Inductance of a aluminum sheet.

Hillman 12 in x 24 in cold rolled steel expanded sheet metal. Grouvers inductance calculations van nostrand new york 1946. The values for ρ are from crc handbook of chemistry and physics 1st student edition 1998 page f 88 and are for high purity elements at 20 c. This calculator is provided free by chemandy electronics in order to promote the flexi box.

The inductance of a coil can be increased by placing a magnetic core of ferromagnetic material in the hole in the center. A low inductance increases the frequency of each short circuit arc cycle and can be useful for pinpointing a narrow bead in some joints. Item 168753 model 11786. See also online calculator inductance of a straight conductor of circular section for the hp 42s inductance of a straight conductor of circular section.

For a coplanar waveguide resonator with 1 5 kω sheet resistance and a kinetic inductance fraction close to unity we measure a quality factor in the order of 700 000 at 20 mk. Mutual inductance between a thin tape and a filament the mutual inductance m tl between a fliament and a thin tape parallel to the fliament such as shown in figure 2 is obtained by putting lj f into 3 and integrating over the width of the thin tape. L d 2 n 2 l 0 45d μh where d is the coil diameter in meters n the number of turns and l the coil length in meters. Regarding current sheet inductance formulas for single layer coils one of the most widely known is the one by wheeler which states after converting to metric units.

What this means to most folks is high inductance is good for thicker metals where good wetting at the toes of the weld is a priority and low inductance works better on thin metal. The inductance is proportional to the square of the number of turns in the coil assuming full flux linkage. Return to calculator index.
