What produces electric and magnetic field Why?

What produces electric and magnetic field Why?

Electric fields are produced by electric charges, and magnetic fields are produced by the flow of electrical current through wires or electrical devices. As current moves through a power line, it creates a magnetic field called an electromagnetic field.

How do electrons produce magnetic?

Magnetism is caused by the motion of electric charges. Each atom has electrons, particles that carry electric charges. Spinning like tops, the electrons circle the nucleus, or core, of an atom. Their movement generates an electric current and causes each electron to act like a microscopic magnet.

How are electric fields produced?

The electric field is produced by stationary charges, and the magnetic field by moving charges (currents); these two are often described as the sources of the field. The way in which charges and currents interact with the electromagnetic field is described by Maxwell’s equations and the Lorentz force law.

How electromagnetic field is produced?

electromagnetic field, a property of space caused by the motion of an electric charge. A stationary charge will produce only an electric field in the surrounding space. If the charge is moving, a magnetic field is also produced. An electric field can be produced also by a changing magnetic field.

What is produced when electricity flows in a conductor?

Electromagnetism is produced when an electrical current flows through a simple conductor such as a length of wire or cable, and as current passes along the whole of the conductor then a magnetic field is created along the whole of the conductor.

What makes a field an electromagnetic field?

An electromagnetic field, sometimes referred to as an EM field, is generated when charged particles, such as electrons, are accelerated. Charged particles in motion produce magnetic fields. When the velocity of a charged particle changes, an EM field is produced.

How do you produce an electric field?

An electric field can be produced also by a changing magnetic field. The mutual interaction of electric and magnetic fields produces an electromagnetic field, which is considered as having its own existence in space apart from the charges or currents (a stream of moving charges) with which it may be related.

How can you make a magnet using electricity?

Making a Compass Magnet Gather supplies. A compass works by indicating north with a magnetized needle that aligns with the earth’s magnetic field. Magnetize the needle. Rub the needle using a magnet, a nail, or a piece of fur, which creates a small electric current. Stick the needle through the cork.

How does an electric field depend on a magnetic field?

The electric field is directly proportional to the flux whereas the intensity of the magnetic field depends on the number of field lines produces by the magnet. In the electric field, the like charges repel each other, and the unlike charges attract each other, whereas in a magnetic field the like poles repel each other and the unlike poles attract each other.

How can a magnetic field be used to create an electric current?

Electric generators rotate coils of wires through magnetic fields created by permanent or electric magnets. As the conducting coils move through the magnetic fields, the electrons in the wires move, creating an electric current.

How can electricity be generated using magnets?

Here’s how it works: A magnetic field pulls and pushes electrons in certain objects closer to them, making them move. Metals like copper have electrons that are easily moved from their orbits. If you move a magnet quickly through a coil of copper wire, the electrons will move – this produces electricity.
