Part B s, what is the induced emf in the If the magnetic field B decreases down to zero in 6 10 triangle? Express your answer using three significant figures and include the appropriate unit. Eind = Value Units Submit Request Answer Part C Figure 1 of 1 PartD Provide Feedback Next > I60

Explanation / Answer

part B)

induced emf in the triangle = change in magnetic flux in the triangle/time taken

induced emf in the triangle = 0.50 * area of the triangle * magnetic field/time taken

induced emf in the triangle = 0.50 * sqrt(3)/4 * 0.30^2 * 0.20/(6 *10^-2)

induced emf in the triangle = 0.065 V

the induced emf in the triangle is 0.065 V
