Question $2$: An iron powder toroid core produced with $35$ p distributed air gap technology has $=25$ o$.$ Since the outer diameter is $30mm,$ the inner diameter is $15mm,$ the thickness is $10mm,$ and Bsat $)=(410-7$

a$)$ Calculate the energy stored in the inductance. $5p$

b$)$ If the inductor is exposed to a maximum total flux of $50$ microvolt.seconds in the circuit in which it is used, determine the appropriate number of turns for this situation. $10p$

c$)$ Calculate the inductance value obtained for this case. $10p$

d$)J=3\frac{A}{m}{m}^2,$ for a fill factor of $30\%,$ the maximum inductance to be made with this core. Determine the current limit$.10p$
