Quick Answer: How will you describe the magnetic field?

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. … The effects of magnetic fields are commonly seen in permanent magnets, which pull on ferromagnetic materials such as iron, and attract or repel other magnets.

What is a magnetic field in simple terms?

The magnetic field is the area around a magnet in which there is magnetic force. Moving electric charges can make magnetic fields. … In physics, the magnetic field is a field that passes through space and which makes a magnetic force move electric charges and magnetic dipoles.

What is magnetic field and how is it represented?

Magnetic fields may be represented by continuous lines of force or magnetic flux that emerge from north-seeking magnetic poles and enter south-seeking magnetic poles. The density of the lines indicates the magnitude of the magnetic field.

What is magnetic field made of?

Magnetic fields are produced by moving electric charges. Everything is made up of atoms, and each atom has a nucleus made of neutrons and protons with electrons that orbit around the nucleus. Since the orbiting electrons ≠are tiny moving charges, a small magnetic field is created around each atom.

What are the characteristics of a magnetic field?

Magnetic fields can be pictorially represented by magnetic field lines, the properties of which are as follows:

  • The field is tangent to the magnetic field line.
  • Field strength is proportional to the line density.
  • Field lines cannot cross.
  • Field lines are continuous loops.

What is another name for magnetic field?

Alternate Synonyms for “magnetic field”:

magnetic flux; flux; field; field of force; force field.

How magnetic field is created?

Any current (movement of electrical charge) will create a magnetic field. Certain materials are capable of realigning the angular momentum of their electrons, and iron is one of them. When the angular momentum of electrons gets aligned, an external magnetic field is created.

What are magnetic fields and their influence?

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. … The effects of magnetic fields are commonly seen in permanent magnets, which pull on ferromagnetic materials such as iron, and attract or repel other magnets.

Why do magnetic fields have lines?

Magnetic field lines are a visual tool used to represent magnetic fields. They describe the direction of the magnetic force on a north monopole at any given position. … One useful analogy is the close connection between magnetic monopoles and electric charges.

Where is the magnetic field strongest?

The magnetic field is strongest at the center and weakest between the two poles just outside the bar magnet. The magnetic field lines are least dense at the center and densest between the two poles just outside the bar magnet.

Why is the magnetic field important?

Significance. The Earth’s magnetic field serves to deflect most of the solar wind, whose charged particles would otherwise strip away the ozone layer that protects the Earth from harmful ultraviolet radiation. … The study of the past magnetic field of the Earth is known as paleomagnetism.

Do magnetic fields have mass?

magnetic fields are produced by charged particles in motion, and depend on the charge and velocity of these particles, but not on their mass.

Are photons affected by magnetic fields?

According to theory of properties of photon, they can not be affected by electric and magnetic fields and it is neutral. But Electromagnetic waves contain electric and magnetic fields .

What are three characteristics of magnetic poles?

Magnetic lines of force have a number of important properties, which include:

  • They seek the path of least resistance between opposite magnetic poles. …
  • They never cross one another.
  • They all have the same strength.

How do the magnetic fields work?

The magnetic field is the area around a magnet that has magnetic force. 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.

What are the 4 properties of magnet?

They are:

  • Attractive Property – Magnet attracts ferromagnetic materials like iron, cobalt, and nickel.
  • Repulsive Properties – Like magnetic poles repel each other and unlike magnetic poles attract each other.
  • Directive Property – A freely suspended magnet always points in a north-south direction.
