The magnetic field intensity (H) of a circular coil is given by
\(H = \frac{I}{{2 R}}\)
Where I is the current flow through the coil
R is the radius of the circular coil
Calculation:
Given that, Current (I) = 2 A
Diameter = 1 m
Radius (R) = 0.5 m
Magnetic field intensity \(H = \frac{2}{{2 \times 0.5}} = 2\;A/m\)
Common Mistake:
The magnetic field intensity (H) of a circular coil is given by \(H = \frac{I}{{2 R}}\)
The magnetic field intensity (H) of a straight conductor is given by \(H = \frac{I}{{2\pi R}}\)Last updated on Jun 16, 2025
