Imagine a hunter in the jungle who has just spotted a monkey grasping a tree branch above him. to avoid more troubling moral questions, let’s assume that the hunter must capture the monkey to treat it for a disease before releasing it back into the wild. the hunter also knows that the monkey will reflexively drop from the branch immediately after the hunter pulls the trigger. immediately after the bullet exits the barrel, the monkey will begin his free fall toward the ground. however, the hunter doesn't know exactly how fast the tranquilizer bullet will travel after leaving the gun — he just knows it'll move fast. with all of this in mind, where should the hunter aim? where would you aim? three choices arise: 1. aim above the monkey2. aim directly at the monkey3. aim below the monkey

the amount of current in the coil

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
