A fixed magnetic field shows flux growing with area across three rows. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

One area unit sets two webers

With field 2 T and area 1 as the area value, flux is 2 Wb.

Φ=2×1=2\Phi=2\times1=2
Magnetic fluxPerpendicular field times area sets flux.B=2 TA=1 m^2Phi=2 Wb

Doubling area doubles flux

With field 2 T and area 2 as the area value, flux is 4 Wb.

Φ=2×2=4\Phi=2\times2=4
Magnetic fluxPerpendicular field times area sets flux.B=2 TA=2 m^2Phi=4 Wb

Four area units make eight webers

With field 2 T and area 4 as the area value, flux is 8 Wb.

Φ=2×4=8\Phi=2\times4=8
Magnetic fluxPerpendicular field times area sets flux.B=2 TA=4 m^2Phi=8 Wb
