One end of a plastic pipe is capped and the other end is open. the pipe stands on the capped end in a magnetic field of 0.030 t that makes an angle of 10° with the vertical. the pipe has an inside diameter of 5 cm. what is the flux through the plastic of the pipe?

magnetic flux = 0.579 × Weber

Explanation:

given data

magnetic field B = 0.030 T

angle ∅ = 10°

diameter d = 5 cm

to find out

flux through the plastic of the pipe

solution

we get here magnetic flux that is express as

magnetic flux = magnetic field × Area × cos∅    ..............1

put here value we get

magnetic flux = 0.030 × × cos10

magnetic flux = 0.030 × × cos10

magnetic flux = 0.030 × 1.9634 × × 0.984

magnetic flux = 0.579 × Weber

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
