An infinitely long, straight wire carrying current �1 passes through the center of a circular loop of wire carrying current �2 , as shown in figure. The long wire is perpendicular to the
plane of the loop. Which of the following describes the magnetic force on the loop?
a) Outward, along a radius of the loop
b) Inward, along a radius of the loop
c) Upward, along the axis of the loop
d) Downward, along the axis of the loop
e) There is no magnetic force on the loop

u=13

v=30

s/t=u+1\2at

=13+431/2

=13+265.5

=278.5

answer: what are you talking about?

explanation:

attach the statements so i can answer : )

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
