Curved Surfaces also reflect light. One example is a Spherical Mirror
... But the current drops to 0 when the magnet stops. Even if it is inside the loops! So the current depends not on B, but the change in B. The strength of the induced current is proportional to the rate at which magnetic field is changing. ...

REVIEW OF COMPLEX NUMBERS
... magnitude is the resistance in ohms and whose angle is 0° In the complex plane, resistance is a phasor that lies along the real axis The rectangular form of resistance is R + j0 Example: The voltage across a 2.2kΩ resistor is v(t) = 3.96sin(2000t + 50°) V. Use phasors to find the current through the ...

Mathematics of radio engineering
The mathematics of radio engineering is the mathematical description by complex analysis of the electromagnetic theory applied to radio. Waves have been studied since ancient times and many different techniques have developed of which the most useful idea is the superposition principle which apply to radio waves. The Huygen's principle, which says that each wavefront creates an infinite number of new wavefronts that can be added, is the base for this analysis.
