Field Distribution And Field Strength For Electrical Lab Training.
Principle
The
magnetic flux density in the field of a straight conductor is inversely
proportional to the distance from the conductor. In the experimental
set-up pictured here, a high-current transformer generates an
alternating current of approximately 100 A, which flows through a
rectangular electrical conductor. In combination with the high
sensitivity of the teslameter, this high current makes it possible to
measure magnetic field strength very precisely at distances up to more
than 10 cm. The series of measurements begins at a distance r of
about 1 cm and increases incrementally to 10 cm at constant current,
whereby the probe is moved along an extended radius of the conductor at a
constant height.
