Linear Current Density Formulas
Basic Formula:
K = I / L
Where K = linear current density, I = total current, L = length
Unit Conversion:
K₂ = K₁ × (f₁/f₂)
Where f₁, f₂ are conversion factors to base unit
Example Calculation:
Convert 50 mA/cm to A/m:
50 × 0.1 = 5 A/m
Magnetic Field:
B = μ₀K / (2π)
Magnetic field from infinite current sheet

Practice Problems
Problem 1:
Convert 25 mA/cm to A/m
Solution: 25 × 0.1 = 2.5 A/m
Problem 2:
Convert 0.5 kA/m to mA/cm
Solution: (0.5 × 1000) ÷ 0.1 = 5000 mA/cm
Problem 3:
Convert 1000 μA/mm to A/cm
Solution: (1000 × 0.001) ÷ 100 = 0.01 A/cm
Problem 4:
A wire carries 2 A current over 50 cm length. Find K in mA/cm
Solution: K = (2 A) ÷ (50 cm) = 40 mA/cm
Problem 5:
Convert 10 A/cm to μA/mm
Solution: (10 × 100) ÷ 0.001 = 1,000,000 μA/mm
Daily Uses of Linear Current Density
Power transmission lines distribute current along their length
Printed circuit board traces carry current per unit width
Electromagnetic coils have current density along wire length
