Magnetic Flux Density - (Measured in Tesla) - Magnetic flux density is equal to the magnetic field strength times the absolute permeability of the region where the field exists. Magnetic flux density formula, B=μH.
Relative Permeability - (Measured in Henry per Meter) - Relative Permeability is the ratio of effective permeability of a particular fluid at a particular saturation to absolute permeability of that fluid at total saturation.
Secondary Turns of Coil - Secondary turns of coil is number of turns of 2nd winding or number of turns of secondary winding of transformer.
Coil Current - (Measured in Ampere) - Coil Current is defined as the flow of electrons through a conductor which is made into a coil by turning it around.
Coil Inner Diameter - (Measured in Meter) - Coil Inner Diameter is defined as the distance the separates the entire circumference of the coil within itself.

## What is a Toroid?

A toroid can be considered as a circular solenoid that is used in an electric circuit, as an inductor at low frequencies when large inductances are required.

The first toroid was invented in 1830 by the physicist Michael Faraday. He noticed that the change in the magnetic field resulted in the voltage in a wire. This phenomenon is known as Faraday’s law of induction.
