P and Q are two infinitely long straight pärallel conductors placed in air 'r' distance apart. Let `I_1` and `I_2` be the current on P and Q respectively flowing in the same direction. Then
a. What is the magnetic field on Q due to `I_1`?
b. What is the force experienced by Q?
C. Is there any attraction or repulsion between P and Q?

`(B_p = (mu_0I)/(2pi r) b. F = (mu_0I_1I_2l)/(2pi r) ` (over a lenght l)
c. Yes There is an attaraction between P and Q.
