Question
Transcribed Image Text:**Problem Statement:**
The core shown below is made of cast iron. Find the coil current necessary to get a flux of 200 kilolines of flux. The cross-sectional area of the core and air gap are both 4 in². The B-H curve for the core is shown below. Fill in the blank below.
**Diagram:**
- The diagram on the right illustrates a magnetic core with a coil wrapped around it. The coil consists of 600 turns.
- The core material is indicated as cast iron with a cross-sectional area of 4 square inches.
- The core has an air gap with a width of 0.2 inches and a total length of 2.5 inches.
**B-H Curve Graph:**
- A graph is shown with 'Field Intensity, H (A-turns/in.)' on the x-axis ranging from 0 to 250.
- 'Flux Density, B (kilogauss)' is on the y-axis ranging from 0 to 130.
- Two curves are plotted on the graph: one for Cast Steel and another for Cast Iron.
**Task:**
Find the current required in the coil to produce a magnetic flux of 200 kilolines in the core.
**Current = _______________ Amps**
