<p>A grain oriented electrical steel having excellent magnetism and a manufacturing method thereof are provided to improve magnetism by controlling Sn, Sb, and P and optimizing cross relation between Sn, Sb, and P. A grain oriented electrical steel having excellent magnetism includes Sn: 0.03-0.07 weight%, Sb: 0.01-0.05 weight%, and P: 0.01-0.05 weight%. The electric steel plate additionally includes Si: 2.0-4.0 weight%, acid solubility Al: 0.020-0.040 weight%, Mn: 0.01-0.20 weight%. The electric steel plate is manufactured from a steel slab including C: 0.04-0.07 weight%, N: 10-55ppm, and S: 0.0010-0.0055%.</p> |
