Faradays Law and Lenz's Law

F_{B} (pronounced phi) is defined as the
magnetic flux for a uniform magnetic field

F_{B}
= B_{perp}A = BAcosq
where B_{perp} is the component of B perpendicular to the loop of
area A and q is
the angle between B and a line

perpendicular to the loop

The angle theta,

degrees, flux is minimum (cos

q
= 0 degrees, flux is maximum (cos
q = 1) |
