Calculate induced EMF from changing magnetic flux

Method 1: Direct Flux Change

Number of Turns (N):

Flux Change (Wb):

Time Change (s):

Method 2: From Magnetic Field and Area

Magnetic Field B (T):

Area (m²):

Initial Angle (degrees):

Final Angle (degrees):

Faraday's Law of Induction

EMF = -N * d(Phi)/dt

Magnetic Flux: Phi = B * A * cos(theta)

Where:

N = number of turns in coil
B = magnetic field strength (Tesla)
A = area of coil (m²)
theta = angle between B and normal to area
