## Main Question or Discussion Point

Hello,

I'm investigating the relation of the length and number of turns of a search coil of a fluxmeter (measure magnetic flux). I got to an equation

B= qR/nA

where q is the quantity of charge passed through search coil

R is the combined resistance of search coil and fluxmeter

n is the number of turns of search coil

A is the cross sectional area of search coil

How can I get the optimum length & number of turns for a search coil?
