A 0.59 T magnetic field is perpendicular to a circular loop of wire with 75 turns and a radius of 18 cm . If the magnetic field is reduced to zero in 0.14 s , what is the magnitude of the induced emf? (Answer should be in V).

Step 1
Given: Number of turns, N = 75 Radius, r = 18 cm = 0.18 m Magnetic field, B = 0.59 T Magnetic flux, Φ = B * A Area of the circular loop, A = π * r^2 A = π * (0.18)^2 A = 0.1018 m^2 Φ = 0.59 * 0.1018 Φ = 0.059962 Tm^2 Show more…

A 0.65-T magnetic field is perpendicular to a circular loop of wire with 73 turns and a radius of 18 $\mathrm{cm} .$ If the magnetic field is reduced to zero in 0.12 s, what is the magnitude of the induced emf?

A circular loop of wire of radius 12.0 $\mathrm{cm}$ is placed in a magnetic field directed perpendicular to the plane of the loop as in Figure $\mathrm{P} 31.3 .$ If the field decreases at the rate of 0.0500 $\mathrm{T} / \mathrm{s}$ in some time interval, find the magnitude of the emf induced in the loop during this interval.
