A magnetic field generates around the wire.
it is known as coil
electromagnet
Electromagnetic induction.
Yes. That is how it is done.AnswerNo, it's a voltage, not a current, that is generated.
Current coil carries the current.
What happens when the current in the coil is halved? No pins are attracted. ... A magnetic field is always created around a wire when it carries electric current.
A magnet created when electric current flows through a coil of wire is called an electromagnet.
electromagnet
A generator moves a coil of wire through a magnetic field and that induces a current in the coil .

The copper wire carries an electric current.
The most common way is with a magnet and a coil of wire. Have either the magnet or the coil (it doesn't matter which) fixed in place and the other one attached to a membrane that will vibrate with the sound. When a magnet moves past a coil of wire, it causes an electric current in the wire.
No field
A magnetic field generates around the wire.
The rotor turns (rotates) causing magnetic fields to move across a coil of wire. This induces an electrical current in the wires of the coil.
