Magnetic Dipole Moment Calculator

Find the magnetic moment of a current loop.

Calculated Output

Magnetic moment (A·m²) 2

Formula: m = N·I·A

Step-by-Step Breakdown

1. Values used:

2. Number of turns = 100

3. Current = 2 A

4. Loop area = 0.01

6. Magnetic moment = (100 / 100) x 2 = 1 x 2 = 2A·m²

Did this calculator solve your problem today?

The math behind it

m = N·I·A, the product of turns, current and loop area.

100 turns, 2 A, 0.01 m² → 2 A·m².

Why does it matter?

It sets the torque a loop feels in an external magnetic field (τ = m × B).
