A classic and ancient experiment is to get a compass, a battery (9volt is fine), and some wire. Notice that the compass changes when the circuit is closed (wire connected to the two terminals). You can also see that the compass gets affected less when it is far from the wire versus next to it.
If your interested in the math behind the experiment, you may want to do some research on the Biot-Savart Law. The Biot-Savart law describe the magnetis field when the current is constant, or not time-varying. A more general form of the equation is called Ampere's Law, and the more general case of that is Maxwell's equations.
What else can I help you with?
Is polarization the source of magnetism?
No, polarization is not the source of magnetism. Magnetism is caused by the alignment of magnetic moments in a material, while polarization refers to the separation of positive and negative charges in a material. Magnetism arises from the movement of electrons in atoms and their alignment in a magnetic field.
Does the magnetic field increase or decrease if the current is decreased?
An increase in an electrical current will cause magnetism to increase but a decrease in an electrical current will cause magnetism to decrease.
What is demagnitising current?
Demagnetizing a current means too take away the magnetism from the current ;)
What is the source of magnetism?
Magnetism is caused by moving electrical charge. Magnetic force is also related to electromagnetism.
Is the earth's core a possible source of magnetism?
yes the molten metals in the core generally produce ions.. when this liquid metal ions flows in the core the constitute sort of current... we know current generates magnetic field.. its the reason for earth magnetism........ you also might heard about the magnetic poles shifting... answer is the same
How can you develop a magnet?
Electric current in a coil can induce magnetism in an iron nail,place near the coil.when the electric current is cut off the magnetism in the iron nail disappears.the magnetism in the nail exist so long as there is electric current in the coil.this is an electromagnet.
Classify magnet according to materials or source of magnetism?

What scientist do to prove and introduce current electricity?
they made inventions to prove that current electricity is there.
If someone asked you to prove that electricity and magnetism were related how would you do it?
To prove that electricity and magnetism are related, I would cite Faraday's law of electromagnetic induction, which shows that a changing magnetic field can induce an electric current in a conductor. Additionally, I would reference Ampère's law, which illustrates that electric currents generate magnetic fields. Together, these principles are encapsulated in Maxwell's equations, demonstrating the fundamental interconnection between electric and magnetic phenomena.
The source of magnetism is?
The source of magnetism is the movement of electric charges. When electrons move through a material, they create a magnetic field. The alignment of these moving charges can result in the material becoming magnetized.
What three things are needed to make an electromagnetic?
Iron, copper wire and dry cell batteries
What will increasing the electric current to an electromagnet do to its magnetism?
An increasing electric current moving into an electromagnet will become stronger in its magnetism. As the atoms align the increasing magnetism will stop at one point, making the electromagnet as strong as it can be.
