Question

Determine the magnitude and direction of the force between two parallel wires 35 m long and 6.0 cm   apart, each carrying 35 A in the same direction.

Answer 1

The magnitude of the force is 0.1429 N.

Step-by-step explanation:

Given that,

Current = 35 A

Distance = 6.0

Length = 35 m

We need to calculate the force

Using formula of force

`F=(\mu_(0)i_(1)i_(2)l)/(2\pi d)`

Where, d = distance

l= length

Put the value into the formula

`F=(4\pi*10^(-7)*35*35*35)/(2\pi*0.06)`

`F=0.1429\ N`

If the current in the same direction then the conductor attract to each other

Hence, The magnitude of the force is 0.1429 N.
