The electromagnet

Series of experiments related to understanding how electric current is generated

Aim:

See a very specific application of the magnetic field generated by electric current.

Material:

• DC power source.
• A piece of soft iron about the size of a pen.
• One meter of insulated electrical conductor (best winding wire).
• Insulating tape

Process:

• Cover the piece of iron with a layer of electrical tape or paper.
• Wrap around it as many turns as you want, the more the better.
• Remove the insulation from the ends of the conductor and connect them to the source.

Then you can do all the experiences that have been developed with magnets.

Write down what happens if a piece of iron is brought close to the electromagnet without the source being connected:
