Unformatted text preview: 234 Chapt. 31 Faraday’s Law of Induction and Inductors a) volts (V=J/C). b) joules (J). c) newtons per coulomb (N/C). d) webers (Wb). e) oersteds (Oe). 031 qmult 00154 1 1 1 easy memory: magnetic flux algebra-based Extra keywords: algebra-based 11. The magnetic flux of uniform magnetic field vector B through a planar area segment of vector area vector A (which has magnitude equal to the area and direction normal to the plane in whichever sense is convenient) is given by: a) Φ = vector A · vector B . b) Φ = A/B . c) Φ = vector A × vector B . d) Φ = B/A . e) Φ = vector A vector B . 031 qmult 00160 1 1 2 easy memory: unique magnetic flux linked 12. The verb used with the subject contour or loop in the context of magnetic flux means that contour bounds a surface area through which magnetic flux is being evaluated. For example, “This wire s the magnetic flux”. This usage of is common, but rarely defined it seems, except by implication....
