3.5*10^-5 N/m is the magnitude of the force between two parallel wires 35 m long and 7.0 cm apart, each carrying 35 A current and the force on each wire will be repulsive.
The number which shows or represents the strength of the force is termed as the magnitude of that force.
Data given :
Two parallel wires
35 m long and 7.0 cm apart,
each carrying 35 A current .
To find the magnitude and direction of current.
f=μ/4π*2[tex]I_{1}[/tex][tex]I_{2}[/tex]/d
f=[tex]10^{-7}[/tex]*2*35*35/7
f=3.5*10^-5
Hence, 3.5*10^-5 N is the magnitude of the force between two parallel wires 35 m long and 7.0 cm apart, each carrying 35 A current.
