This formula uses 5 Variables

Variables Used

Former Length - (Measured in Meter) - Former Length is the total height of former.
Former EMF - (Measured in Volt) - Former EMF is defined as the electric potential produced by either an electrochemical cell or by changing the magnetic field.
Magnetic Field - (Measured in Tesla) - Magnetic Field are produced by electric currents, which can be macroscopic currents in wires, or microscopic currents associated with electrons in atomic orbits.
Former Breadth - (Measured in Meter) - Former Breadth is defined as the distance or measurement from side to side of the former.
Former Angular Speed - (Measured in Meter per Second) - Former Angular Speed is defined as the distance of the body covers in terms of rotations or revolutions to the time taken.

STEP 1: Convert Input(s) to Base Unit

Former EMF: 0.122683 Volt --> 0.122683 Volt No Conversion Required
Magnetic Field: 4.763 Tesla --> 4.763 Tesla No Conversion Required
Former Breadth: 4.2 Meter --> 4.2 Meter No Conversion Required
Former Angular Speed: 10.5 Meter per Second --> 10.5 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

l_f = emf/(2*B*b*ω) --> 0.122683/(2*4.763*4.2*10.5)

Evaluating ... ...

l_f = 0.000292035212853425

STEP 3: Convert Result to Output's Unit

0.000292035212853425 Meter --> No Conversion Required

FINAL ANSWER

0.000292035212853425 ≈ 0.000292 Meter <-- Former Length

why we are maintain the gap voltage in vibration probe ?

The EDDY current generates between the vibration probe tip and the shaft area. Increasing and decreasing the area by the shaft will make the measurement of vibrations. So it needs to be done during the installation.
