Q1- The magnetic circuit shown is made of a cast-steel and has a coil of 1000 turns on its 5cm and the center limp. The center limp and each of the side limbs has a width of thickness of the core t =5 cm . The means length of magnetic paths limp=30 cm. Determine the current that the coil should carry to produce a flux of 2.5 mWb in the air-gap. Neglect magnetic leakage and fringing. The magnetization curve fore steel is given LABCD=LAFED= 60 cm, and the length of center cast- B (flux density) Wb/ mm? 0.2 0.5 0.7 1.0 1.2 by: (Amper-turn/ 300 540 m) H 650 900 1150 B 0.1 cm 60cm 60 cm 30 cm 5 1000 Trun 5 Is D

Type of Magnetic Material

Every material has a unique composition that defines its magnetic behavior. Some materials get attracted towards a magnet and are called magnetic materials. Based on the magnetic properties held by each material, they are classified into different types.
