pub fn magnetic_pressure_kernel<R>(
    b_field: &PhysicalField<R>,
    permeability: R,
) -> Result<MagneticPressure<R>, PhysicsError>
where
    R: RealField + FromPrimitive,

Calculates magnetic pressure. $$ P_B = \frac{B^2}{2\mu_0} $$

Arguments

• b_field - Magnetic field $B$.
• permeability - Magnetic permeability $\mu_0$.

Returns

• Result<MagneticPressure<R>, PhysicsError> - Magnetic pressure $P_B$.
