What is the difference between conductors and insulators?
Conductors are materials that allow electric current to flow through them easily due to the presence of free electrons, while insulators are materials that inhibit the flow of electric current due to their high resistance.

See lessDefine magnetic permeability.
Magnetic permeability is a measure of a material's ability to conduct magnetic flux. It determines how easily magnetic lines of flux can pass through the material and is measured in henries per meter (H/m).

See lessDefine electric potential difference.
Electric potential difference, also known as voltage, is the difference in electric potential energy per unit charge between two points in an electric field. It is measured in volts (V) and represents the work done per unit charge in moving a charge between the two points.
