Easily calculate the magnetic field (B) generated by a magnetic dipole moment (μ) at a specific radius (r). Our precise online calculator helps physicists, engineers, and students quickly determine magnetic field strength, crucial for understanding electromagnetic interactions and designing magnetic systems.
Formula:
The magnetic field (B) of a magnetic dipole moment (μ) at a distance (r) along its axis is given by the formula:
B = (μ₀ / 2π) * (μ / r3)
Where:
- B = Magnetic Field (Tesla, T)
- μ = Magnetic Dipole Moment (Ampere-meter squared, A·m²)
- r = Radius or Distance from the center of the dipole (meters, m)
- μ₀ = Permeability of Free Space (approx. 4π × 10-7 T·m/A)
Therefore, (μ₀ / 2π) simplifies to 2 × 10-7 T·m/A, making the calculation straightforward.
