What is the EMF induced when the magnetic field changes from 2.3 T to 0.5 T in 10 seconds with a 2 m by 4 m rectangular conductor positioned perpendicular to the field?

Answer 1

Answer 2

emf = -ΔΦ/Δt

ΔΦ = (ΔB)A

ΔB = (0.5 - 2.3)T

A = (2)(4) m²

Δt = 10s

You have everything you need. Plug the numbers into the equation for emf. Be careful with signs.

Answer 3

emf = -ΔΦ/Δt

ΔΦ = (ΔB)A

ΔB = (0.5 - 2.3)T

A = (2)(4) m²

Δt = 10s

You have everything you need. Plug the numbers into the equation for emf. Be careful with signs.
