Student Exploration: Electromagnetic Induction
Vocabulary: current, electric field, electromagnetic induction, magnetic field, magnetic flux,
right-hand rule, vector, voltage, wind generator
Prior Knowledge Question (Do this BEFORE using the Gizmo.)
A wind generator, such as the one shown at left, uses the
power of wind to generate electricity. What do you think is
happening inside the wind generator to convert the energy of the
spinning blades into electricity? Make your best guess.
I think the wind generator is adding potential energy and
kinetic energy to mechanical energy. Then maybe a coil or motor
converts that into electrical energy.
Gizmo Warm-up
Usually when you experiment with circuits, you use a
battery or another energy source to create a current. But
is it possible to generate a current without a battery?
You can find out with the Electromagnetic Induction
Gizmo.
In the Gizmo, you can drag the wire loop around or use
the controls to move the magnet up and down. You can
also rotate the wire loop. Experiment with the Gizmo to
see how many different ways you can create a current in
, the wire loop and light the light bulb. Describe your
findings below.
If I make the magnet go up and drag the light bulb closer
then the light will turn on.
