How to calculate
Integrate the sinusoidal induced-voltage law using RMS voltage and peak magnetic flux density.
Vrms≈4.44288294 f N A Bpeak; coefficient=2π/√2
Worked example
At the same winding voltage, frequency, turns and area, doubling the turn count halves modeled peak flux density.
Assumptions and input details
Sinusoidal induced winding voltage, negligible winding drops/leakage and uniform effective core area. Coefficient is the exact sine-wave value 2π/√2 rather than rounded 4.44. No material saturation limit, core loss, insulation or transformer build/rating recommendation.
Unit definitions
Unit selection is independent of language. Each selector contains only units for its physical quantity. Calculations use defined base units internally.
SI prefixes are explicit: for example, milli means one thousandth, micro one millionth and kilo one thousand. Changing a unit changes the interpretation of the entered number.
Using this calculator
Can I enter my own problem?
Yes. Replace the example values with your own inputs. The result, calculation steps, tables and applicable diagrams update from those inputs. Blank or invalid values clear the result; example values are never silently substituted for missing inputs.
Are the results exact?
Results use floating-point arithmetic and displayed rounding. Read the formula, assumptions and any stated data precision before interpreting the result.
Is my input uploaded?
The calculation runs in your browser. No account, file upload or external AI service is required. Inputs are not saved between page reloads.
Calculate the ideal AC voltage ratio and a simplified efficiency-based current and power balance. Keep ideal voltage scaling separate from entered losses.
Convert tesla, gauss, microtesla and nanotesla for the same magnetic flux-density value.
Calculate time-weighted mean, total RMS, AC-only RMS and crest factor from irregularly timed voltage samples under an explicit interpolation model.
