Physics: Examining Faraday's Law, how could it be altered to account for a magnetic field that is not perpendi?
Examining Faraday's Law, how could it be altered to account for a magnetic field that is not perpendicular to the plane formed by the loop of conductor?
Be as detailed as possible. will be quick to award BA, thanks in advance for any help

When the direction of the magnetic flux (F) vector is not perpendicular to the plane of the coil you insert a factor cos(a) where a is the angle between the direction of F and the normal to the plane.
V = cos(a)*dF/dt
or V = cos(a)*A*dB/dt where A is the area of the coil and the magnetic flux density B is assumed to be uniform over A.
Note that this answer is given in terms of F & B. Your question asks about the magnetic field (H). You can use the relationships I have given with B replaced by u*H where u is the permeability of the medium in which the field is measured (u0 for air or vacuum).
