Magnetic Field Calculator for Loop Antennas
Use this tool to calculate the magnetic field strength of a loop antenna based on its diameter, number of windings, applied current, and measurement distance. Results are provided in multiple units, including A/m, Tesla, Gauss, and dBµA/m.
dBµA/m: 0.00
pT: 0
dBpT: 0.00
Tesla: 0
Gauss: 0
A/m: 0
Formula:
H = (N * I * r²) / (2 * (R² + r²)^(3/2))
Where:
- H = Magnetic field strength (A/m)
- N = Number of windings
- I = Current (A)
- r = Loop radius (m)
- R = Distance from loop (m)
This tool helps with:
Determining the magnetic field strength of loop antennas in various measurement units.
Analyzing field distribution based on loop size, applied current, and distance.
Supporting RF and EMC testing by providing accurate field strength values.
