Is the magnetic flux passing through an area Φ = BA or is it Φ = nBAcosθ? both right, sort. BA would be the answer when the field is normal to the plane. nBACos[theta] would be the answer for a coil of N turns at some angle theta to the field. 10/07/2018 · The next video is starting stop. Loading. Watch Queue. 20/12/2019 · A circular loop with 30 turns and area of 0.25 eqm^2 /eq rotates at 100 rad/s. The axis of rotation of the loop is perpendicular to the direction of the magnetic field of 0.04 Tesla. What is the maximum emf induced in the loop? eq\beginalign \Phi = NBA\cos \theta \endalign /eq eq\begin.

13/11/2007 · Physicsfilter: Is the magnetic flux passing through an area Φ = BA or is it Φ = nBAcosθ? I just sat a Physics exam and my friend and I are not too sure which is the correct answer. He asked some teachers, but the answers at the time of writing aren't very satisfactory. Fluxo magnético através de uma superfície. O campo magnético → que atravessa a superfície forma um ângulo com elemento infinitesimal de área → normal à superfície. Solution Obtain the expression for the emf induced in the rotating coil of N turns each of cross-sectional area A, in the presence of a magnetic field B Concept: Ac Generator.

Magnetic induction In the previous section we learned about the magnetic field, how it is caused by current carrying wires and its effects on other current carrying wires. In this chapter we will learn how a changing magnetic fields can produce an electromotive force – how changing currents in one wire can induce a current in another wire.

26/07/2007 · a coil of wire with 10 turns and an area of 0.055 m^2 is placed in a magnetic field of 1.8T and oriented so that the area is perpendicular to the field. the coil is then flipped by 90 degrees in 0.25 s and ends up with the area parallel to the field. coswtΦ and coswt both shows the wave nature I.e. the oscillating nature of the particle. Here Φ shows the phase difference between the position of the particles on the wave. If we say that the distance between the particle A & B on the wave i. I'm looking at the following problem from "Physics 3" by Halliday, Resnick and Krane 4th edition: The armature of a motor has 97 turns each of area 190 cm² and rotates in a uniform magnetic field of 0.33 T.
