- Reduc eddy current losses

- we use laminated core

- Hysteresis loss: use of soft magnetic material with law hystersis

- [ Si- steel, steel alloys , Mn-Bn ferrites]

- $V = V_m sin \omega t$

- I = $\frac {V_m}{L_\omega} .sin (\omega - \frac {\pi}{2})$

- current lags the voltage by $\frac {\pi}{2}$

- $ I_m = \frac {V_m}{L_\omega}: L_\omega = X_L $ inductive reactance

- ELI the ICE man.

- Z = $\sqrt {R^2 + (X_L - X_c)^2}$

- For $X_L = X_c$ : Z has a minimum

- By varrying $\omega$, we get a maximum amplitude where

- $\omega = \omega_0 = \frac {1}{\sqrt LC} $ Resonant frequency

- $R_1 > R_2 > R_3$
