Acircular loop with a 0.03-m radius and 18-ω resistance is facing away from this page. a magnetic field that points into the page was 0.35 t one second ago and is now 0.25 t. what current (in which sense of circulation) appears in this loop, if any?

15.7 x 10⁻⁶ A

Explanation:

r = radius of the circular loop = 0.03 m

Area of the loop is given as

A = πr² = (3.14) (0.03)² = 0.002826 m²

R = Resistance of the resistor = 189 Ω

ΔB = Change in magnetic field = 0.25 - 0.35 = - 0.10 T

Δt = time interval = 1 sec

Current is given as

i = 15.7 x 10⁻⁶ A

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
