An electric generator has an 18 -cm-diameter, 120 -turn coil that rotates at 60 in a uniform magnetic field that is perpendicular to the rotation axis. What magnetic field strength is needed to generate a peak voltage of 170 ?
The magnetic field strength is
The magnetic field lines has been the portion of magnetization which thus goes through one loop of across By This magnet is calculated on the basis:
The magnet is given by if the magnetism makes an equal with axis.
The rotation's pitch is represented by the sign f. Whereas a coil's diameter is d = 18 cm, the length equals
From Faradays, the mediated is the modification of the magnetization in there in the spiral and this is provided by the type
Because the magnetosphere is diagonally to the axis of rotation, the word "perpendicular magnetic field" is used.
