this is a story

2.) All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.

3.) The properties of magnets are used to make electricity. ... Moving a magnet around a coil of wire, or moving a coil of wire around a magnet, pushes the electrons in the wire and creates an electrical current. Electricity generators essentially convert kinetic energy (the energy of motion) into electrical energy.

4.) When current flows through a wire, a magnetic field is produced around the wire and an electromagnet is formed. The magnetic field can be turned off again by switching off the current. Around every magnet there is an invisible magnetic field.

5.) Yes, Because Electromagnetism has important scientific and technological applications. It is used in many electrical appliances to generate desired magnetic fields. ... It has many more technological applications including MRI scanning (magnetic resonance imaging) and electric bells.

Answer:

Explanation:

1. What is electromagnetism?

=Electromagnetism is a branch of physics involving the study of the electromagnetic force, a type of physical interaction that occurs between electrically charged particles. At high energy the weak force and electromagnetic force are unified as a single electroweak force.

2.How does a magnet work?

=Opposite poles are attracted to each other, while the same poles repel each other.

3.How does electricity work on magnets?

= Moving a magnet around a coil of wire, or moving a coil of wire around a magnet, pushes the electrons in the wire and creates an electrical current. Electricity generators essentially convert kinetic energy (the energy of motion) into electrical energy.

4.How do you off electromagnet?

=When current flows through a wire, a magnetic field is produced around the wire and an electromagnet is formed. The magnetic field can be turned off again by switching off the current. Around every magnet there is an invisible magnetic field.

5.Do you think electromagnetism is important in today technology?How?

=Electromagnetism has important scientific and technological applications. It is used in many electrical appliances to generate desired magnetic fields. ... It has many more technological applications including MRI scanning (magnetic resonance imaging) and electric bells.
