The longitudinal path of magnetic field lines is due to the formation of the loop from the lines.

The magnetic field lines in the solenoid follow the longitudinal path, hence, these magnetic field lines must move in the opposite direction outside the solenoid.

Magnetic field lines are present in the form of loops, wherein they cannot diverge or converge to a point compared to electric field lines. Moving Charges and Magnetism Important Questions

With increasing H, B tends to saturate as there is a limit value of induction when all the magnetic dipoles align with the field of material required. The permeability is the ratio of flux density in the material (B) and the flux density in the air (H): in other words is the measure of the relative ease with which a magnetic flux is established, the symbol that represents it is the Greek letter μ (μi = micro index). The salient features of these nuclei are: the size, the permeability (μ), the frequency range and maximum power. The magnetic materials used for the construction of the toroidal cores are many but the two main ones are: iron powder (iron powder) and the ferrite. The toroidal cores (Amidon is one of the major manufacturers) have extensive application in radio frequency circuits and power supplies. The factor of merit (or quality) expressed with the letter Q is the ratio of the reactance (inductive in this case) and the sum of all the losses associated with the decrease in energy in transit Air Core Calculator Program The ballast is an electrical resistance element that offers to the passage of an alternating current having a certain frequency. L ‘inductance is the ability to store electrical energy in an electromagnetic field.
