Transcribed Image Text:1.The long, straight conductor shown in Fig. 1 lies in the plane of the rectangular loop at a
0.5 m, and the currents are
distance d
0.1 m. The loop has dimensions a = 0.2 m and b =
= 40 A andI2 = 30 A. Determine the net magnetic force acting on the loop.
I =
b =0.5 m
|d =0.1 m a =0.2 m
Figure 1:
2. An 8cm x 12cm rectangular loop of wire is situated in the x-y plane with the center of the
loop at the origin and its long sides parallel to the x- axis. The loop has a current of 50 A flowing
clockwise (when viewed from above). Determine the magnetic field at the center of the loop.
3. A unit normal vector from region 2(u = 2µo) to region 1(µ = µo) is
an21 =
((6a, + 2a, – 3a:)/7)
If
H1
10а, + a, + 12a, A/m
and
Н2 3D Һ2ла, — 5а, + 4а, А/m
determine
(a)H2r
(b) The surface current density K on the interface
(c) The angles B1 and B2 make with the normal to the interface.
4.A very long solenoid with 2 x 2 cm cross section has an iron core (ur = 1000) and 4000
turns/meter. If it carries a current of 500 mA, find
(a) Its self-inductance per meter
(b) The energy per meter stored in its field
5. For the solenoid filled with a magnetic material determine the bound current densities.
