You are given 13.0 m of thin wire. You form the wire into a circular coil with 70 turns. If this coil is placed with its axis parallel to a 0.12 T magnetic field, what is the flux through the coil? Express your answer with the appropriate units.
Added by Samuel C.
Step 1
We know that the length of the wire is equal to the circumference of the coil times the number of turns. The formula for the circumference of a circle is 2πr, so we have: 13.0 m = 2πr * 70 Solving for r, we get: r = 13.0 m / (2π * 70) ≈ 0.029 m Show more…

Figure $P 25.16$ shows a 100 -turn coil of wire of radius $12 \mathrm{cm}$ in a $0.15 \mathrm{T}$ magnetic field. The coil is rotated $90^{\circ}$ in $0.30 \mathrm{s}$, ending up parallel to the field. What is the average emf induced in the coil as it rotates?
