The size of a magnetic field. Measured in Webers (Wb) |
|
|
Define magnetic flux density |
The strength of a magnetic field measured in teslas. |
|
|
Define magnetic flux linkage |
The magnetic flux passing through a coil of wire (Wb). |
|
|
Define turns |
Complete loops on a coil of wire |
|
|
Define search coil |
A small coil of wire placed in a magnetic field in order to measure the properties of the field |
|
|
Define induced EMF |
The voltage induced due to a change in magnetic flux in a wire |
|
|
Define peak voltage / current |
Maximum voltage / current of an AC supply |
|
|
Define root mean Square voltage / current |
Average voltage / current of an AC supply |
|
|
Define peak to peak voltage / current |
the difference between the maximum positive voltage / current and the maximum negative voltage / current in an AC supply |
|
|
Define eddy currents |
A current induced in a conductor by changing magnetic flux |
|
|
Define laminated core |
the core of a transformer, motor or generator which is made from thin slices of soft iron with a magnetic insulator between them. This reduces the size and effect of eddy currents. |
