Notes - 23-1-23-2 Induction, Flux and Faraday’s Law
1. When generating power, the voltage/potential difference is known as
___________________________________________.
2. The basic process of generating emfs and, hence, currents with magnetic fields is
known as ___________________.
3. It is the change in __________________ field that creates the current. The
current flows because there is an ____________. In summary, the current is a
result of an emf induced by a changing magnetic field.
4. Last class we saw that a current flowing
through a coil will cause it to rotate in a
magnetic field. Conversely, if a coil is rotated
within a magnetic field, ____________ will
flow. This is the basis for
________________________________.
5. Any combination of a change in the magnetic field strength, the area of the coil or the
orientation of coil in the magnetic field will generate a current. Together, magnetic
field strength, area and orientation of the coil to the magnetic is summarized in the
term _____________________________.
B =
6. Faraday’s Law: Any change to the magnetic flux produces an emf which produces a
current.
emf =
