# Lab work: measuring Kerr effect

1. The problem statement, all variables and given/known data

the main idea is this i have an 'Alternate current' I which i know the intensity

I have also 2 Helmholtz plates of radius 'R' separated by a distance 'R' (the separation between plates is equal to their radius )

then by magnetic induction the alternate current 'I' we will create a magnetic Field 'B' which i must measure using a Hall probe

2. Relevant equations

$$\oint B .dl = cI$$ (c is a constant) that is the Field 'B' depends on the current

3. The attempt at a solution

I know that the current is alternating and know the Intensity (i suppose that $$I=I_0 Sin(ut)$$ or something similar , since is a lab work i do not know what else to do
