Answer 2

Your complete question is- A current of 10 A is established in a long wire along the positive Z-axis. Find the magnetic field vector B at the point (1m, 0, 0).

Magnetic field vector B at the point (1m, 0, 0) is 2μT along positive Y direction.

Given-

• Current = 10 A
• Distance = 1 m

We know that magnitude of magnetic field vector can be given by -

B = μ₀i/2πr where i is the current and r is the radius.

By substituting the value we get

B = 10⁻⁷ × 4π × 10 /2π × 1 = 2 μT along positive Y direction
