A 10 cm long bar that hangs like a swing on two 4 m long threads is placed In a homogeneous magnetic field of a flux density of 1.5 T. The forces are perpendicular to the bar (see the figure below).
Explain how the induced voltage changes with time if the bar oscillates harmonically with an amplitude of 8 cm.
When and where is the induced voltage greatest?
The bar oscillates harmonically in a homogeneous magnetic field
