3B Scientific Induction Tube Apparatus with 6 Coils - Manual (Page 2)

2
By using the 3B NETlog TM unit as an interface or by
means of a storage oscilloscope it is possible to
display the voltage curve graphically. Two 4 mm
sockets are provided for making the connections.
After falling, the magnet is held in the rubber
washer and can be retrieved when the plinth is
tilted sideways. The cork mat serves to protect the
magnet and the table top from damage by the
impact.
2. Technical data
Coil width: 5 mm
Distance between coils: 180 mm
Number of turns: 13 in each coil
Overall dimensions: 130x200x1020 mm 3 approx.
Weight: 500 g approx.
3. Assembly
• Set up the tube in the socket of the plinth using
gentle pressure.
Bumps, knocks or any lateral forces acting on the
tube may damage the instrument.
• Do not subject the tube to any mechanical
stress.
4. Operation
Also required:
1 3B NETlog TM U11300-230
or
1 3B NETlog
TM U11300-115
1 3B NETlab TM U11310
Experiment leads
• Set up the experiment as shown in fig. 1.
• Connect leads between the connector sockets of
the tube and the voltage input U
A
IN on the
interface.
• Connect the interface to the computer.
• Start the software program.
• Hold the bar magnet over the top opening of
the tube.
• Start a measurement in the program and allow
the bar magnet to fall.
• Evaluate the voltage curve.
Alternatively, the measurement may be carried out
with an oscilloscope.
