Making a magnet

A series of experiments related to understanding how electric current is generated

Aim:

See how steel acquires permanent magnetic properties.

Material:

• A direct current source.
• A coil of 300 turns.
• A piece of steel that can be inserted into the coil.

Process:

• Carry out the assembly as shown in the picture.
• Insert the steel inside the coil.
• Switch on the source for a moment.
• Check that the steel has acquired the property of attracting ferrous materials.

Tip:

• Replace the coil connection.
• Insert the steel.
• Switch on the source for a moment.

Observe and record what happens:
