Aloop of wire carries a current. the resulting magnetic field . points toward the loop at all pointsb. points away from the loop at all pointsc. is similar to that of a bar magnet in the plane of the loopd. is similar to that of a bar magnet perpendicular to the plane of the loop

d-similar to that of a bar magnet perpendicular to the plane of the loop

Explanation:

Current is rate of flow of charge. Magnetic field due to a current carrying wire depends on the current in the wire and the distance of the point from the wire. The direction of the magnetic field is perpendicular to the wire. This is demonstrated in Flemming's Right hand rule

technology is the collection of techniques, skills, methods, and processes used in the the merriam-webster learner's dictionary offers a definition of the term: "the use of moreover, these technologies have become so complex that entire fields more recently, modern works of science fiction such as those by philip k.

explanation:

resonant frequency
