Print Calculator bal Periodic Table 2 Question 15 of 16 Map Sapling Learning The component of the external magnetic field along the central axis of a 46-turn circular coil of radius 39.0 cm decreases from 2.40 T to .450 in 3.10 Š. If the resistance or the coil is 1.50 , what is the magnitude of the induced current in the coil? Number What is the direction of the current if the axial component of the field points away from the viewer? O clockwise O counter-clockwise Hint O Prevaus Gve Up View Soliton O check Answer Ex- Next

Explanation / Answer

Here ,

N = 46

r = 0.39 m

induced current in the loop = pi * r^2 * N * change in magnetic field/R

induced current in the loop = 46 * pi * 0.39^2 * (2.4 - 0.450)/(3.1 *1.50)

induced current in the loop = 9.21 A

as the field is decreasing , the induced current is counter clockwise
