## Homework Statement

ok i have a lab w a magnetic balance (where u have weight on one side and electrical magnetism on the other) and its using a law :

F=(u x i

^{2}x l)/(2 x (pi) x d)

were i is intensity, l is lenght of hte conductors, separated by a distance d, u is 4π×10-7 kg·m·A-2·s-2

this is a derivative of biot savart law

now they are asking me to transform the formula to have I

^{2}/m (m is mass

how do i do this?

oh and my data is

1 lenght of string is 5cm long and has a volumic mass of 0.14567 g/m

# of 5 cm lenghts / i

1 2.48

2 4.39

3 4.92

4 5.66

5 5.88

6 6.81

7 7.41

8 7.87
