1. A potential field is given by the expression: in free space. Find the stored energy density in 1 m3 volume centered at origin. 2. A scalar field is given as W= 1.5x2+ 1.2 x2y- 0.05yz3. Find the magnitude of gradient of this field at (2,-2,1)m 3. A magnetic toroid, 0.05 m in diameter and 1.5 cm2 sectional area of the copper core has a uniform winding of 700 turns. If the flux density in the copper core is to be 3mT and relative permeability μr of copper core is 50, calculate: i. The exciting current required to be passed in the winding; ii. The value of self-inductance; and iii. The stored energy. 4. With the help of a neat diagram explain what uniform plane waves are and also mention the properties of it. بلييييييييز الي يعرف الحل بكرة اخر يوم
