Waltenhofen Pendulum For Electrical Lab Training Description and Specifications for Lab Tenders
Waltenhofen Pendulum For Electrical Lab Training.
Principle
When
a massive body made of conductive material moves through a magnetic
field, eddy currents are induced. According to Lenz’s law, the body is
then subjected to a force which is opposed to the cause of the eddy
currents, i.e. the motion of the pendulum. The braking action increases
with the strength of the magnetic field. If slits are cut into the body,
this reduces the generation of the eddy currents.
