Physics>> Magnetism >> Relation between electricity and magnetism Electricity is the property of charged particles such as electrons and protons.
Thus, the magnetism also cancels out. Relationship between electricity and magnetism In the early days scientists believed that, electricity and magnetism are two separate forces. However, after the publication of James Clerk Maxwell, these forces are treated as interrelated forces. InHans Christian Orsted observed a surprising thing, when he switched on the battery from which the electric current is flowing, the compass needle moved away from the point north.
After this experiment, he concluded that, the electric current flowing through the wire produces a magnetic field. Electricity and magnetism are closely related to each other.
The electric current flowing through the wire produces a circular magnetic field outside the wire. The direction clockwise or counter-clock wise of this magnetic field is depends on the direction of the electric current.
In the similar way, a changing magnetic field produces an electric current in a wire or conductor. The relationship between electricity and magnetism is called electromagnetism. It's impossible for both of the electrons in a pair to spin in the same direction.
This is part of a quantum-mechanical principle known as the Pauli Exclusion Principle.
Electrons and Why Magnets Stick | HowStuffWorks
Even though an atom's electrons don't move very far, their movement is enough to create a tiny magnetic field. Since paired electrons spin in opposite directions, their magnetic fields cancel one another out. Atoms of ferromagnetic elements, on the other hand, have several unpaired electrons that have the same spin. Iron, for example, has four unpaired electrons with the same spin. Because they have no opposing fields to cancel their effects, these electrons have an orbital magnetic moment.
The magnetic moment is a vector -- it has a magnitude and a direction.Electricity & Magnetism
It's related to both the magnetic field strength and the torque that the field exerts. A whole magnet's magnetic moments come from the moments of all of its atoms. An iron atom and its four unpaired electrons In metals like iron, the orbital magnetic moment encourages nearby atoms to align along the same north-south field lines.
Iron and other ferromagnetic materials are crystalline. As they cool from a molten state, groups of atoms with parallel orbital spin line up within the crystal structure.
This forms the magnetic domains discussed in the previous section. You also know that positive charges are attracted to negative charges.
Understanding the Relationship Between Magnetism and Electricity
A French scientist named Andre-Marie Ampere studied the relationship between electricity and magnetism. He discovered that magnetic fields are produced by moving charges current. And moving charges are affected by magnets. Stationary charges, on the other hand, do not produce magnetic fields, and are not affected by magnets. Two wires, with current flowing, when placed next to each other, may attract or repel like two magnets.

It all has to do with moving charges. Earth's Magnetic Field Magnets are simple examples of natural magnetic fields. The Earth has a huge magnetic field. Because the core of our planet is filled with molten iron Fethere is a large field that protects the Earth from space radiation and particles such as the solar wind. When you look at tiny magnets, they are working in a similar way.
The magnet has a field around it.
