Challenge Problems
Push your limits with challenges.
Question 1
A magnetic core has an area of 0.005 m² and a total reluctance of 3000 AT/Wb. Calculate the MMF required to establish a flux of 0.001 Wb in this core.
💡 Hint: Make sure to relate reluctance and flux correctly.
Question 2
You are designing a transformer that requires an MMF of 600 AT. If the winding has 400 turns, what is the minimum current that must flow through the coil?
💡 Hint: Apply the MMF formula and solve for I.
