Magnetic Dipole Moment Calculator

Your details

Choose the physical object whose magnetic dipole moment you want to calculate.
Choose how to specify the area of the current loop.
Electric current flowing through the loop or solenoid coil.
A
Radius of the circular current loop in metres.
m
Radius of each circular turn in the solenoid in metres.
m
Enable to enter an external magnetic field and compute torque and potential energy.
Magnetic dipole moment
1.5708A·m²

Strength of the magnetic dipole

Effective loop area0.7854m²
Magnetic dipole moment (A·m²)1.5708
Effective area (m²)0.7854

Magnetic dipole moment: 1.5708 A·m²

  • This is in the range of a typical bar magnet or small industrial electromagnet.
  • The dipole model is most accurate at distances greater than twice the largest dimension of the source.

Next stepToggle 'Include external field' to compute the torque and potential energy your dipole experiences in a given field.
