To find the intensity of the magnetic field at the axis of the wire, we can use Ampere's law. Ampere's law states that the magnetic field around a closed loop is proportional to the current passing through the loop.
The formula for the magnetic field at the axis of a long, straight wire is given by:
B = (μ₀ * I) / (2π * r)
where B is the magnetic field, μ₀ is the permeability of free space (4π × 10^-7 T·m/A), I is the current, and r is the distance from the wire.
In this case, the current (I) is given as 2 A and the radius (r) is given as 2 mm (or 0.002 m).
Plugging these values into the formula, we get:
B = (4π × 10^-7 T·m/A * 2 A) / (2π * 0.002 m)
Simplifying the equation gives:
B = (4π × 10^-7 T·m) / (2π * 0.002 m)
B = (2 × 10^-7 T·m) / (0.004 m)
B = 5 × 10^-5 T
Therefore, the intensity of the magnetic field at the axis of the wire is 5 × 10^-5 T.
