What is a magnetic field? Magnetic field Properties

What is a magnetic field?

The area around a magnet as far as its magnetic effect can be experienced. So it is called the magnetic field of that magnet. Or we can say that. That area where the magnet is able to influence its attraction power on some iron material. So it is called the magnetic field of that magnet.

What is the intensity of magnetic field and magnetic field?

An imaginary independent unit located at a point in an area experiences about the same force as the North Pole. It is called the intensity of the magnetic field at that point.

Magnetic force lines

The magnetic force line is the curved path. At which an independent unit can travel north pole.

Properties of magnetic force lines

• The magnetic force lines exit the North Pole and enter the South Pole.
• Two magnetic force lines never cross each other.
• The magnetic force lines are dense.
• The magnetic force lines resemble the elastic cord, which attempts to shrink.
• A tangent drawn to a point of magnetic force lines represents its resultant at that point.

Properties of magnetic field lines

• Magnetic field lines are continuous closed curves.
• The closer the magnetic field lines are, the stronger the magnetic force lines.
• The magnetic field lines never cut each other.
• What is the unit of intensity of magnetic field?
• The unit of intensity of the magnetic field is Newton / ampere-m (Tesla).
