Frequently Asked Questions on Magnetic Circuits
What is the core of magnetic circuit made up of?
The core of circuit is made up of magnetic materials. Some of the examples are iron and soft steel.
How does the flux change with increased number of turns in solenoid?
From the formula of flux (ø =NI) it is directly proportional to number of turns hence magnetic flux increases with increased number of turns.
Can we use wood as the core of solenoid?
No, we specifically choose a magnetic material as the core of solenoid due to its properties like permeability. Other materials like wood can’t show magnetic behaviour hence we can’t use it.
Can ohm’s law be applied to magnetic circuits?
It is not possible to apply ohm’s law to magnetic circuits rather we can apply and equivalent version of ohm’s law known according to which the number of magnetic force lines(Φ) is proportional to the magnetomotive force (Fm) and inversely proportional to the circuit’s reluctance (Rm).
Magnetic Circuits
Till now we have talked about standard circuits like linear and non-linear circuits but in the electronics industry, there are another kind of circuits called ‘magnetic circuits’. These circuits like any other circuits have a closed path but the path is followed by magnetic lines of forces creating a field of magnetic flux instead of a flowing current. In this article, we will study what are magnetic circuits, and what components make up the circuit. We will also represent the equation used to represent these circuits mathematically. Later we will discuss the need of having magnetic circuits and some applications of magnetic circuits in everyday life. We will conclude the article by summing up what we have learned. The electronics industry especially the communication system uses these signals in various circuits and readers can read about these other signals as well.
