Question

what are magnetic field lines? state four properties of magnetic field lines ​

Answer 1

Answer:

Magnetic field lines are imaginary lines around the magnet. The magnitude of a field is indicated by its line's density. Near to South and North Pole of a magnet, the magnetic field is stronger and will get weaker when it moves away from the poles.

Four properties of Magnetic Field are:

1] The field is tangent to the magnetic field line.

2] Field strength is proportional to the line density.

3] Field lines cannot cross.

4] Field lines are continuous loops.

Answer 2

Answer:

Magnetic field lines are imaginary lines around the magnet.

magnitude of a field is indicated by its lines density.

Properties of magnetic field line

• field is tangent to the magnetic field line.
• field strength is proportional to the line density.
