A Flat Circular Coil Has 200 Identical Loops of Very $0.12 \mathrm {~m} ^ { 2 }$

question 32

Multiple Choice

A flat circular coil has 200 identical loops of very thin wire. Each loop has an area of $0.12 \mathrm {~m} ^ { 2 }$ and carries $0.50 \mathrm {~A}$ of current. This coil is placed in a magnetic field of $0.050 \mathrm {~T}$ oriented at $30 ^ { \circ }$ to the plane of the loop. What is the magnitude of the magnetic torque on the coil?

• A) \(2.5 \mathrm {~N} \cdot \mathrm { m }\)
• B) \(0.25 \mathrm {~N} \cdot \mathrm { m }\)
• C) \(0.52 \mathrm {~N} \cdot \mathrm { m }\)
• D) \(5.2 \mathrm {~N} \cdot \mathrm { m }\)

Anabolic Reactions

Biochemical processes in cells that synthesize complex molecules from simpler ones, requiring energy, and crucial for growth, repair, and storage.

Catabolic Reactions

Catabolic Reactions are metabolic processes that break down molecules into smaller units, releasing energy stored in chemical bonds.

Energy

The capacity to do work or produce heat; it exists in various forms such as kinetic, potential, thermal, electrical, chemical, nuclear, and mass energy.

Basal Metabolic Rate

The rate of energy expenditure by the body at rest to maintain vital functions.
