Question

5. What is the force in between two parallel conductors? Why they attract each other? Problem-5: Calculate force between two parallel conductors each of length 1 m, and carrying current 15 A in +y direction? (Distance between two is 0.2 um)

Answer 1

WI W2 otto Suppose there are two conductors, wire wi, wil we carrying current i, el respectily in the same direction The distance between the wires is 'd' Now it we observe the wire wy, there is electic current in in. vertically upward direction . Using Right hand thumb Rake , there is magnetic field in the night of wire, wa pointing upward (corning out of paper, o) e in given by I le 3 Moi Td Now, this magnetic field exerts a magnetic force (f = 19 x 8) on he wire, wl Similar in the case for wire wr. so, if we take the length of both wires be 'l , Then force between them is: to с но, і, 1 QTd

We are julen = Im i =i= IS A da 0.2 mm - 0.2x 106m IF 24 Mox Pizl UT - 2x107x 15x15x1. smo - 107 w/A2L I UT o-2x106 [F= 225n] f = २२5N
