Consider a Cartesian coordinate system (x,y,z).
Suppose a uniform H
field of 1 A/m exists in the direction of the xaxis.
Calculate the MMF drop from
the point (1,1,0) to the point (4,3,1).
2.)
15 pts. Consider a Cartesian coordinate system (x,y,z).
A uniform Bfield of 1 T
exists along the direction of the xaxis.
Now consider the rectangular plane
bounded by the points (2,0,0),(0,0,2),(0,2,2),(2,2,0).
How much flux is traveling
through the rectangular plane.
3.)
15 pts. Consider a toroid with a rectangular cross section of 1 cm by 1 cm.
The
