ε = B*Lemf*v
This formula uses 4 Variables
Variables Used
Electromotive Force - (Measured in Volt) - Electromotive force is the capability of the system to make the charge flow.
Magnetic Field - (Measured in Tesla) - Magnetic fields are produced by electric currents, which can be macroscopic currents in wires, or microscopic currents associated with electrons in atomic orbits.
Length - (Measured in Meter) - Length is the measurement or extent of something from end to end.
Velocity - (Measured in Meter per Second) - Velocity is a vector quantity (it has both magnitude and direction) and is the rate of change of the position of an object with respect to time.
STEP 1: Convert Input(s) to Base Unit
Magnetic Field: 2.5 Weber per Square Meter --> 2.5 Tesla (Check conversion here)

Motional EMF Formula

Electromotive Force = Magnetic Field*Length*Velocity
ε = B*Lemf*v

What is motional EMF ?

An emf induced by motion relative to a magnetic field is called a motional emf. When an electrical conductor or an object is introduced into a magnetic field B, due to its dynamic interaction with the magnetic field, emf e is induced in it. This emf is known as induced emf.

How to Calculate Motional EMF?

Motional EMF calculator uses Electromotive Force = Magnetic Field*Length*Velocity to calculate the Electromotive Force, The Motional EMF formula is defined as the electromotive force in terms of magnetic field, length of the object moving at speed v relative to the strength of the magnetic field B. Electromotive Force is denoted by ε symbol.

How to calculate Motional EMF using this online calculator? To use this online calculator for Motional EMF, enter Magnetic Field (B), Length (Lemf) & Velocity (v) and hit the calculate button. Here is how the Motional EMF calculation can be explained with given input values -> 45 = 2.5*3*6.
