Magnetic Field Strength Calculator


The magnetic field strength differs greatly upon the type of device or properties. Below are the online magnetic field strength calculators to find around a wire, magnetic field strength inside a loop and magnetic field inside a solenoid.

Firstly, the formula to calculate magnetic field strength around a wire is given by:

Magnetic Field Strength around a Wire Formula


where, 
B = Magnetic field strength [Tesla]
k = Permeability of free space (2x10^-17)
i = Current [amps]
L = Distance from wire [meters]

Current (i): amps
Distance from Wire (L): meters
Magnetic Field Strength Around Wire (B): Tesla




The formula to calculate magnetic field strength inside a loop is given by:

Magnetic Field Strength Inside a Loop Formula


where,
N = Number of coils
r = Coil radius [meters]
