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 i2 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 I2/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
