u_B=B^2/(2mu)
What you receive
What you receive
- Magnetic energy density in J/m^3 from the stated equation
- A symbolic formula plus substituted working with your values
- Visible assumptions, field guidance, and an authoritative learning reference
Use boundary
Choose the maximum decimal places shown. This does not increase source accuracy.
The medium is linear and isotropic with the supplied permeability.
Use internally consistent units and retain extra precision when carrying the result into another calculation.
