 | **Inductance per turn** | High | Low |
 | **Saturation Current (I_sat)** | Low (saturates easily) | High (resists saturation) |
+| **Knee** | Sharp and abrupt | Gradual and soft |
 | **Core Losses (AC/Ripple)** | Higher (high AC flux density) | Lower (flatter magnetization slope) |
 | **Winding (Copper) Losses** | Lower (requires fewer turns) | Higher (requires more turns) |
 | **Typical Materials** | High-nickel alloys, MnZn ferrites | Powdered iron, gapped ferrites, Kool Mμ |

+===== Saturation current =====
+In the middle of the knee
+===== Inductor value =====
+Inductor value can be calculated as follows:
+  H = V * s / A
+  where H is Henry, V is voltage over inductor, s is time, A is current at time is s.
+===== Formula =====
+  v = L * (di/dt)
