Card Set Information
The ability of a substance to be magnetized upon application of a magnetizing force
The flux per unit area
the strength of a magnetic field represented by lines of force
Magnetomotive force per unit length of a magnetic circuit
The driving force in a magnetic circuit that establishes flux
A measurement of the opposition of a material to the establishment of the magnetic field
Alternating current flowing in the primary of a transformer creates an alternating
, which establishes an alternating flux in the core.
The mmf is calculated as the
of the coil
and number of turns. The flux, according to
law is the
of the coil mmf to the reluctance of the core.
law, the alternating flux induces a voltage across the secondary winding. Secondary current flows when a load is connected across the secondary terminals.
The load current, according to
law is calculated as the
of the induced voltage and the load
