Magnitude and direction of the force between two parallel wires
Answer to Problem 30P
0.0729N
Attractive
Explanation of Solution
Given:
Length of parallel wires is 35 m.
Separation distance is 6 cm.
Current carried is 25 A in same direction.
Formula used:
Force is given as
Here,
I1 and I2 are current in two wires.
d is distance between two wires.
l is length of each wire.
Calculation:
Here l =35m, I1 = I2 =25A, d =6.0cm=0.06m
As, the current in two parallel wires are in same direction, the force is attractive.
Conclusion:
Therefore, force is 0.0729 N and attractive in nature.
