last attempt on each question please help?

question 1:

Two rigid rods are oriented parallel to each other and to the ground. The rods carry the same current in the same direction. The length of each rod is 0.64 m, while the mass of each is 0.090 kg. One rod is held in place above the ground, and the other floats beneath it at a distance of 7.6 mm. Determine the current in the rods.

question 2:

The magnetic field produced by the solenoid in a magnetic resonance imaging (MRI) system designed for measurements on whole human bodies has a field strength of 5.52 T, and the current in the solenoid is 2.76

Explanation / Answer

A. apply gravitational force   =   force between the wires

i,e mg = u0i1i2/2pid

or i1i2 = mg * 2pid L/(u0)

i1i2 = i^2 = 0.09*9.8 * 2* 3.14* 0.0076*0.64/(2pi*10^-7)

i2 = sqrt(42900.48)

i2 = i1 = 207.13 Amps

b. alpply B = u0 ni

n = N/L = 5.52/(4pi*10^-7 * 276)

n = 15923.56 turns /meter
