4.5 Dependency of the induced voltage on the
number of turns and the speed of the induc-
tion loop
• Set up the experiment as specified in 4.4.
• Connect the multimeter initially to the tap
socket for 800 turns and measure the induced
voltage.
• Repeat the experiment at the same applied
voltage with 1600 and 2400 turns, and measure
the corresponding induced voltages.
• Compare the induced voltages.
The induced voltage is proportional to the number
of turns.
• Connect the multimeter to the tap socket for
2400 turns.
• Set the applied voltage to 4 V and measure the
induced voltage. Observe the speed of the flat
coil.
• Repeat the experiment at voltages of 6 V, 8 V
and 10 V.
• Compare the induced voltages.
The induced voltage is proportional to the speed of
the coil.
