Online Calculators since 2009
The Faraday's Law Calculator will calculate the:
Calculation Parameters: Magnetic field and medium are considered as uniform; the conducting wire used for the coil is uniform and it has the same thickness everywhere.
|The Emf induced in the coil is V [Volt]|
|Emf induced in the coil calculation|
|εi = -B × (A2 × cosθ2 - A1 × cosθ1)/∆t|
εi = - × ( × cos() - × cos())/∆t
εi = - × ( × - × )/∆t
εi = - × /∆t
εi = -/∆t
|Faradays Law Calculator Input Values|
|Magnetic field (B) T [Tesla]|
|Initial area of coil punched by magnetic field lines (A1) m2 [square metre]|
|Final area of coil punched by magnetic field lines (A2) m2 [square metre]|
|Initial angle formed by magnetic field lines and area vector (θ1) rad [radian]|
|Final angle formed by magnetic field lines and area vector (θ2) rad [radian]|
|Time taken to change the position of coil (Δt) s [secomd]|
Please note that the formula for each calculation along with detailed calculations are available below. As you enter the specific factors of each faradays law calculation, the Faradays Law Calculator will automatically calculate the results and update the Physics formula elements with each element of the faradays law calculation. You can then email or print this faradays law calculation as required for later use.
