## 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 e = Blv where B is the magnetic field, l is the length of the object moving at speed v relative to the strength of the magnetic field B. Electromotive Force and is denoted by ε symbol.

How to calculate Motional EMF using this online calculator? To use this online calculator for Motional EMF, enter Length (l), Magnetic Field (B) and Velocity (v) and hit the calculate button. Here is how the Motional EMF calculation can be explained with given input values -> 450 = 2.5*3*60.

### FAQ

What is Motional EMF?
The Motional EMF formula is defined e = Blv where B is the magnetic field, l is the length of the object moving at speed v relative to the strength of the magnetic field B and is represented as ε=B*l*v or Electromotive Force=Magnetic Field*Length*Velocity. Length is the measurement or extent of something from end to end, Magnetic fields are produced by electric currents, which can be macroscopic currents in wires, or microscopic currents associated with electrons in atomic orbits. and Velocity, in physics, is a vector quantity (it has both magnitude and direction), and is the time rate of change of position (of an object). .
How to calculate Motional EMF?
The Motional EMF formula is defined e = Blv where B is the magnetic field, l is the length of the object moving at speed v relative to the strength of the magnetic field B is calculated using Electromotive Force=Magnetic Field*Length*Velocity. To calculate Motional EMF, you need Length (l), Magnetic Field (B) and Velocity (v). With our tool, you need to enter the respective value for Length, Magnetic Field and Velocity and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
