Question

The headlight of a bicycle is powered by a small generator connected to the wheel of the bicycle; the generator contains two fixed coils connected in series with appropriate polarity. Each coil consists of 70 turns and has an area of 8.0 sq. cm. A small permanent magnet is mounted between the coil. Field strength varies between 0.1T and 0T. At what bicycle speed will the EMF = 6.4V?

Answer 1

GIVEN:

Two Coils

\[N = 70\]
\[A = 8.0 cm^2\]
\[\left| \Delta B \right|= 0.1 \tau\]
\[\xi = 6.4V\]
Find the linear velocity (bicycle speed).
