Final answer:
To find the magnetic field intensity (H) in all space using Ampere's law, follow these steps: Choose a closed path, calculate the total current passing through the enclosed surface, apply Ampere's law, and solve the equation to find H for all points in the space.
Step-by-step explanation:
Ampere's law is used to calculate the magnetic field intensity (H) generated by current in a wire.
To find the magnetic field intensity (H) in all space, follow these steps:
- Choose a closed path that encloses the region where you want to find the magnetic field intensity.
- Calculate the total current passing through the surface enclosed by the chosen path.
- Apply Ampere's law, which states that the line integral of the magnetic field around a closed path is equal to the product of the total current passing through the enclosed surface and a constant called the permeability of free space.
- Solve the equation obtained from Ampere's law to find the magnetic field intensity (H) for all points in the space.
