How to read your Magnetic Flux result

Magnetic flux is the total magnetic field passing through a surface. The SI unit is the weber, one volt-second. One maxwell is exactly 1×10⁻⁸ Wb.

Common mistakes when calculating Magnetic Flux

  • Confusing flux (Wb) with flux density (T).
  • Mixing mWb and µWb, which differ by 1,000.
  • Mixing the maxwell with the gauss.

Magnetic Flux FAQ

How many Wb is 1 Mx?

Exactly 1×10⁻⁸ Wb.

How is weber related to tesla?

1 Wb = 1 T × 1 m², flux density times area.

How many µWb is 1 mWb?

1 mWb is 1,000 µWb.

What is the base unit for magnetic flux?

This converter uses weber (Wb) as the common base unit: every value is first converted to it and then to the target unit.

How do I convert between two magnetic flux units?

Choose the starting and target units, enter the value and read the result. By hand: convert to the base unit with the table, then divide by the target unit factor.

How many milliwebers are in 1 weber?

1 Wb = 1,000 mWb.

How many maxwells are in 1 weber?

1 Wb = 100,000,000 Mx.

How many microwebers are in 1 weber?

1 Wb = 1,000,000 µWb.

Which magnetic flux units does this converter support?

It covers 8 units: weber (Wb), milliweber (mWb), microweber (µWb), maxwell (Mx), kilomaxwell (kMx), volt second (V·s), tesla square meter (T·m²), gauss square centimeter (G·cm²).

How accurate is the magnetic flux converter?

Results are calculated at full double precision and shown to about 8 significant figures. Round the answer to the precision of your original measurement; a result cannot be more accurate than the number you started with.
