Calculator for

Off-Axis Fields Due to a Current Loop
This JavaScript calculator uses the formula for off-axis fields due to a current loop to calculate the axial and radial field components, in Teslas, resulting from a single circular current filament. Enter the loop radius and current, in meters and amperes, respectively, then click "Recalculate Field" to calculate the resulting fields.
Loop Radius (a, meters)  
Loop Current (i, amperes)  
Axial Position at Measurement Point (x, meters)  
Radial Position at Measurement Point (r, meters)  
     
Axial Field Component (Bx, Tesla)  
Radial Field Component (Br, Tesla)
