What is piezoelectric crystal?
Piezoelectricity is the property of a material to generate movement from an electric current, and vice versa. A common piezoelectric material is quartz.
What happends when an electric current passed through a piezoelectric crystals?
They physically change shape.
Are there any materials that undergo strong contraction when an electric current is introduced?
Yes, all piezoelectric materials exhibit the reverse piezoelectric effect. A piezoelectric material is one that generates an electric field or electric potential in response to applied mechanical stress. Therefore, in the reverse case, passing an electric current through the material or an electric potential across the material, will cause it to contract or elongate, depending on the direction of the current. One of the best example of this is lead zirconate titanate which will contract/elongate up to about 0.1% of the original dimensions.
What does electric current?
transmitission of current produce an electric field.and it produce power
What does electric current do?

What can electric current produce?
Voltage. Or, if you prefer, electromotive force (emf). What creates voltage? Electromagnetic action. Electrochemical action. Piezoelectric effect. Photoelectric effect. Thermoelectric effect. Contact electrification (static electricity). What was left out? BREAKDOWN produce in a crystal
What does electric current produce?
A electric current produces a magnetic field
What animal can produce an electric current?
There are eels that can produce an electric shock. They are called electric eels.

Can moving electrons through a magnetic field can produce an electric current?
Electrons moving is an electric current. An electric current moving at an angle to a magnetic field will produce a Force.
What does dynamo produce?
It produces an electric current.
What is needed to produce electromagnets?
electric current
