Question

A conducting loop of wire enclosing an area of 7.1 m².

A. Generates no current
B. Generates a constant current
C. Generates an alternating current
D. Generates a direct current

Answer 1

Without specifying the magnetic field conditions, it's uncertain if a conducting loop will generate a current. A constant or varying magnetic flux is necessary for inducing direct or alternating current, respectively.

Step-by-step explanation:

The subject of the question pertains to electromagnetism, specifically Faraday's Law of electromagnetic induction and its implications for a conducting loop when exposed to a varying magnetic field. The generation of current in a conducting loop depends on the change in magnetic flux through the loop, according to Faraday's Law.

A direct current (D) occurs if there's a steady change in magnetic flux, while alternating current (C) is induced if the change in magnetic flux varies periodically. As the question does not specify a changing or constant magnetic field, the answer would remain undetermined without additional context. However, if the magnetic field remains static, the loop will not generate a current (A).
