(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

a magnet that weighs 2.6 grams is dropped through a 1.53 metre tube. the average time taken for it to go through is 1.59 seconds.

I need to find the strength of the magnetic field and the current

2. Relevant equations

Fg=mg

B=F/Ilsintheta

3. The attempt at a solution

Fg=0.025N[down]

Fsum=0.0031N[down]

Fm=0.023N[up]

I=?

B=?

l=1.53m

Fm=0.023N
