Apparatus: Inductor; coils, magnets, galvanometer and alligator clips.
Description:
Demonstrates
that
current
is
induced
in
a
coil
by
flux
in
a
magnetic
field.
Connect
the
6V
dry
cell
to
the
inductor.
Sparks
are
generated
between
the
two
wires.
Alternatively,
connect
a
coil
to
the
terminals
of
the
galvanometer,
move
a
magnet
through
the
coil.
The
needle
on
the
galvanometer
will
oscillate,
amplitude
and
speed
of
which
depends
on
speed
of
magnet
through
the
coil.
