A uniform 1.5-T magnetic field passes perpendicularly through the plane of a wire loop 0.30 m² in area.What flux passes through the loop? A) 0.135 T⋅m² B) 5.0 T⋅m² C) 0.45 T⋅m² D) 0.25 T⋅m²

Question

Quizplus · Accepted Answer

The flux passing through the loop is given by the formula:
Φ = B A cosθ

where B is the magnetic field strength, A is the area of the loop, and θ is the angle between the magnetic field and the normal to the loop.

Here, the magnetic field is perpendicular to the loop so θ = 0° and cosθ = 1. Thus, the flux passing through the loop is:

Φ = (1.5 T)(0.30 m2) = 0.45 T⋅m2

Therefore, the best choice is C.
