A coil of wire is connected to a galvanometer as shown. A magnet is held stationary above the coil. Under what circumstances will the galvanometer indicate a current?
Homework Answers
When a bar magnet is comes towards a galvanometer,an induced current is set-up in the coil due to change of magnetic field through it. As a result, galvanometer gives a deflection.
If the bar magnet is held stationary above the galvanometer,
then there is no induced current in the coil,
because there is no change in magnetic field through it. As a
result, galvanometer does not show any deflection.

Procedure: Take one of the coils and connect it to the
galvanometer. Use the cylindrical magnet to generate a changing
magnetic field around the coil and note the reading of the
galvanometer as the field changes. Thrust the N pole of the magnet
into the coil and note the effect on the galvanometer. When the
needle has come to rest, withdraw the magnet as quickly as
possible. Note the effect on the direction of current flow. Reverse
the magnet and...

The coil of wire in a galvanometer has a resistance of RC = 75.0 Ω. The galvanometer exhibits a full-scale deflection when the current through it is 0.200 mA. A resistor is connected in series with this combination so as to produce a voltmeter. The voltmeter is to have a full-scale deflection when it measures a potential difference of 14.0 V. What is the resistance of this resistor?
