Tesla is a unit of Flux density.
Through which the magnetic lines of force can pass very easily
A permeable substance is one Through which the magnetic lines of force can pass very easily.
The materials having low retentivity are suitable for making Temporary magnet.
From north pole to south pole
The direction of magnetic lines of force is From north pole to south pole.
Magnetic field intensity
proportional to the square of current
The two conductors of a transmission line carry equal current in opposite directions. The force on each conductor is proportional to the square of current.
A material which is slightly repelled by a magnetic field is known as Diamagnetic material.
The magnetic lines of force will bend away from their usual paths in order to go away in order to pass through the piece
Direction of force on a current carrying conductor in a magnetic field
The ratio of intensity of magnetisation to the magnetisation force is known as Susceptibility.
It has low permeability
Current, magnetic field and direction of force on a conductor
It is dimensionless
Distance between the conductors
The force between two long parallel conductors is inversely proportional to Distance between the conductors.
High permeability and low hysteresis loss
