Hi, in the given problem, there is a closed surface in the form of a prism.
00:13
Those sides are along x, y, and z -axis.
00:21
Here this is x -axis, this is y -axis and this is the z -axis.
00:30
The sides of the prism are given as this one having a length of 50 centimeter the height along y axis 30 centimeter then again this is 50 centimeter this 30 centimeter and these two sides are 40 and 30 centimeter each.
01:08
So this is 40 and 30 and magnetic field in this region is a long that axis.
01:27
Here this is the magnetic field.
01:37
The magnitude of this magnetic field is given as 0 .128 tesla.
01:46
Vertices of this prism are marked as a, b, c and b, c and b, and f.
02:08
In the first part of the problem we have to find the magnetic flux.
02:13
By link through the surface a, b, c, d as this surface a, b, c, d is along the magnetic field as this surface is also lying along z -axis and magnetic field is also along z -axis.
02:50
So, the angle between the magnetic field and normal drawn at the surface a, b, c, is theta, is equal to 90 degree.
03:30
Hence, flux phi to a, b, c, d, will be given by the dot product of magnetic field with the area of this surface a, b, c, d...
