Electromagnetic Induction (HSC SSCE Physics): Flashcards

Amount of magnetic field passing through a given area

$\Phi = BA\cos\theta$

Weber (Wb)

$1\text{ Wb} = 1\text{ T m}^2$

$\theta = 0°$ (field perpendicular to area)

$\Phi_{\text{max}} = BA$

$\theta = 90°$ (field parallel to area)

Change $B$ (field), $A$ (area), or $\theta$ (angle)

Scalar (but can be positive or negative)

Angle between magnetic field and normal to area
