... There are 2 types of generators: AC & DC A wire loop rotated in MF by external means (i.e. crank) As loop rotates, motion of wire loop changes in the magnetic field and thus an induced current is produced The end of loop connected to slipring commutator Connections to external circuit made by statio ...

Lab2: E/M Ratio
... In this experiment you will measure e/m, the ratio of charge to mass of the electron. This is the experiment that J.J. Thomson did at the Cavendish Laboratory in Cambridge in 1897, for which he received the Nobel Prize in 1906. The setup (Fig. 1) consists of a visible beam cathode ray tube used to p ...

The Earth`s magnetic field
... Changing electric fields cause magnetic fields. An electromagnetic wave is created by the changing electric field of a spark, an antenna, or an oscillating molecule (greenhouse gas). The changing electric field then creates a changing magnetic field. ...

WEEK 3-4: DIRECT CURRENT GENERATOR
... • In DC series generators field winding is connected in series with armature and load. Hence, here load current is similar to field current. Thus, the loading characteristic curve is close to the machine magnetization curve. At no load, there is no field current, so VT is reduced to a small level gi ...
