Why are magnetic field lines concentric?

The magnetic field produced due to a straight current carrying conductor is in the form of concentric circles. The centre of the circles lies on the conductor itself and are in the plane perpendicular to the straight conductor. This implies that the magnetic field produced due to straight current is circular.

Why are magnetic field lines discrete?

1) There aren’t enough iron filings to heap up along the infinite possible magnetic field lines. 2) In the trade-off between the magnetic field and the force of friction (provided by the surface on which the iron filings are placed), all of the infinite field lines don’t get to have iron filings heaped on them.

Are magnetic field lines discrete?

No, a magnetic field is not a discrete bunch of lines. Field lines are real in the same sense that the arrows are, or the contour lines on a map. They aren’t just a picture – they genuinely represent something mathematical about the field.

Why are magnetic field lines curved?

Magnetic field lines are closed curves as they propagate from the North pole outside the magnet’s body to the magnet’s body and from the south pole to the north pole inside the magnet’s body. Hence, the magnetic field lines are closed.

Why does the concentric circles becomes big loops in a magnetic field around a current-carrying straight wire if it’s distance increases?

We know that the magnetic field produced by a current-carrying straight wire depends inversely on the distance from it. Similarly at every point of a current-carrying circular loop, the concentric circles representing the magnetic field around it would become larger and larger as we move away from the wire.

Is magnetic field concentric circles?

The Magnetic field lines around a straight conductor carrying current are concentric circles whose centres lie on the wire. The direction of magnetic field lines can be determined using Right-Hand Thumb Rule.

Are magnetic field lines discrete or continuous?

Because the intrinsic magnetism of the filings modifies the field, the lines shown by the filings are only an approximation of the field lines of the original magnetic field. Magnetic fields are continuous, and do not have discrete lines.

Why magnetic field lines are known as non terminating curves?

A magnetic field has no sources or sinks (Gauss’s law for magnetism), so its field lines have no start or end: they can only form closed loops, extend to infinity in both directions, or continue indefinitely without ever crossing itself.

What do the concentric circles represent?

It represents the notions of totality, wholeness, original perfection, the Self, the infinite, eternity, timelessness, all cyclic movement, God (‘God is a circle whose centre is everywhere and whose circumference is nowhere’ (Hermes Trismegistus).

Why do concentric circles become larger and larger when we move away from the centre of current carrying conductor?

by bending At every point of a current-carrying circular loop, the concentric circles representing the magnetic field around it would become larger and larger as we move away from the wire. Draw the pattern of magnetic field lines through and around a current-carrying wire.

Why does the concentric circles becomes big loops in a magnetic field around a current carrying straight wire if it’s distance increases?
