Induced EMF from a changing flux, two ways

The same calculation run twice, side by side. Change anything on either side and the difference is shown output by output. This page is a link: both sets of numbers are in the address bar.

Side A open alone

Number of turns in the pickup coil.

µWb

How much the flux through one turn changed — e.g. the swing read off the flux calculation.

ms

How long that change took.

Side B open alone

Number of turns in the pickup coil.

µWb

How much the flux through one turn changed — e.g. the swing read off the flux calculation.

ms

How long that change took.

Swap sides

What changed

The two sides are the same. Change something on either.

Output A B B against A
ε Induced EMF -500 mV -500 mV same

Side A, with its numbers

-500mV=5050µWb5ms
LaTeX
-500\,\mathrm{mV} = -50 \frac{50\,\mathrm{µWb}}{5\,\mathrm{ms}}

Side B, with its numbers

-500mV=5050µWb5ms
LaTeX
-500\,\mathrm{mV} = -50 \frac{50\,\mathrm{µWb}}{5\,\mathrm{ms}}
