Q: For a cylindrical conductor of radius R carrying current I, what is the magnetic field at a point outside the cylinder?
Solution:
For points outside the cylinder, B = μ₀I/2πr.
Steps: 5
Show Steps
Step 1: Understand that we have a cylindrical conductor with a certain radius R and it carries a current I.
Step 2: Identify that we want to find the magnetic field (B) at a point that is outside the cylinder.
Step 3: Recall that for a long straight conductor, the magnetic field at a distance r from the center can be calculated using a specific formula.
Step 4: The formula for the magnetic field outside the cylindrical conductor is B = μ₀I / (2πr), where μ₀ is the permeability of free space.
Step 5: Note that 'r' is the distance from the center of the cylinder to the point where you want to measure the magnetic field.
