What is the Magnetic Flux Converter?
MRI machines, transformers, and electric motors all run on magnetic flux — the total magnetic field passing through an area — measured in webers in the SI system. One weber is a hefty unit: a powerful MRI magnet holds flux measured in single-digit webers. The older CGS system used the maxwell instead, and the bridge between them is a clean 100,000,000 — one weber equals 10^8 maxwells. That factor of a hundred million is why the maxwell survives: it keeps everyday magnet measurements in comfortable numbers instead of tiny decimals.
Type your value in the Weber (Wb) box and the Maxwell (Mx) readout multiplies by 100,000,000, with the Unit Flux (emu) column matching it exactly — the electromagnetic unit of flux is defined identically to the maxwell. The 1-weber example gives 100,000,000 Mx, the anchor that shows why engineers switched: "1 Wb" beats "100,000,000 Mx" in a report. A refrigerator magnet's flux is on the order of microwebers — millionths of a weber, or hundreds of maxwells. Electrical engineering students converting textbook problems, hobbyists winding coils, and technicians reading vintage equipment nameplates (which often quote maxwells) all multiply or divide by 10^8. The direction is easy to keep straight: webers are the big unit, maxwells the small one.
With the pre-filled defaults — Weber (Wb) 1 — the Magnetic Flux Converter returns Maxwell (Mx) 100,000,000.00, Unit Flux (emu) 100,000,000.00. Change any input and those results update instantly, so you can see exactly how each number you enter moves the answer.
How to Use the Magnetic Flux Converter
- 1Type your flux value in the Weber (Wb) box — start with 1.
- 2Read the Maxwell (Mx) result: 100,000,000 Mx.
- 3Check the Unit Flux (emu) box: identical to maxwells, 100,000,000.
- 4Try a small value like 0.000001 Wb (a fridge magnet) to see 100 Mx.
- 5Remember the direction: webers are big, maxwells are small — multiply going down.

Calculation Progression Roadmap
How the Magnetic Flux Converter turns your inputs into a result, step by step — from the values you type to the answer you read.
Gather your inputs
Type in your Weber (Wb). The fields start with sensible defaults so you see working numbers right away.
Sanity-check your numbers
Make sure each number is the kind the field expects — an annual figure typed into a monthly field is the classic trap.
The math runs itself
The calculator evaluates Weber (Wb) × 100000000 on every keystroke — there is no submit button to press.
Read your results
Your Maxwell (Mx) and Unit Flux (emu) appear instantly. With the pre-filled defaults, that is Maxwell (Mx) 100,000,000.00, Unit Flux (emu) 100,000,000.00. Change any input to see the effect immediately.
Test a what-if
Nudge one input up or down. Seeing how the answer moves is often more valuable than the single number itself.
Real-World Examples
Fresh scenarios — starting with everyday conversions — worked through with different numbers than the examples above, so you can watch the formula handle new situations.
Everyday conversions
Enter Weber (Wb) 2 — the answer comes out to Maxwell (Mx) 200,000,000.00, Unit Flux (emu) 200,000,000.00.
Travel planning
For Weber (Wb) 0.5, expect Maxwell (Mx) 50,000,000.00, Unit Flux (emu) 50,000,000.00.
Following a recipe
A quick run with Weber (Wb) 1.5 gives Maxwell (Mx) 150,000,000.00, Unit Flux (emu) 150,000,000.00.
