Generating EMF by Varying the Magnetic Flux (VCE SSCE Physics): Flashcards

Changing magnetic field creates current in conductor

Changes in magnetic flux, not flux itself

$\Phi_B$

$\Phi_B = B_\perp A$

Weber (Wb) or T m²

$\varepsilon = -N\frac{\Delta\Phi_B}{\Delta t}$

Electromotive force (potential difference at terminals)

Induced flux opposes the change that produced it

Represents opposition to the change

Produces larger current
