Question

Define Magnetic field. Write the properties of magnetic field line produced by bar magnet.
please answer it according to class 10th ncert book​

Answer 1

Answer:

The area around a magnet where the influence of a magnet can be experienced is called magnetic fields. It has both magnitude and direction and the magnetic field and its field and direction are represented by magnetic lines of force. Properties of magnetic lines of force are:

They are continuous closed curves.

They originate from the North Pole and terminate at the South Pole.

Two lines do not intersect each other.

They are crowded where the magnetic field is strong, i.e. near the poles.

Answer 2

Answer:

A magnetic field refers to a vector field in the neighbourhood of a magnet, electric current or charging electric field. ... The moving electric charges and intrinsic magnetic moments of elementary particles connected with a basic quantum property which we call the spin produces this field.
