Why are magnetic field lines of current carrying circular loop appear to be straight line at the centre?

Explanation: At every point of current carrying circular loop the concentric circles representing the magnetic field around it becomes larger and larger as we move away from the wire. At the centre of the loop the field appears as straight line.

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.

Does a straight wire produces magnetic field lines in the shape of concentric circles?

The magnetic field lines would be concentric circles with the wire passing through the centre perpendicular to the plane of the circles.

What is the magnetic field around a straight current carrying wire?

The magnitude of the magnetic field produced by a current carrying straight wire is given by, r = 2 m, I = 10A.

Why magnetic field lines are straight?

At every point of current carrying circular loop the concentric circles representing the magnetic field around it becomes larger and larger as we move away from the wire. At the centre of the loop the field appears as straight line. At the centre of the circular loop, The magnetic field lines are straight.

Can magnetic field lines be straight?

There can’t be such straight field lines between magnetic poles as the magnetic field can always form closed loops. However the tangential vectors through each loops point in the same direction which is illustrated in the figure.

How does circular loop carrying current behaves as a magnet?

The direction of the magnetic field produced is given by right hand thumb rule, where thumb gives direction of the current and curled fingers give the direction of the magnetic field produced. Hence the current carrying circular loop behaves like a magnet.

What will happen to the magnetic lines of force of the field produced by a current flowing through a loop made by bending the straight wire?

The magnetic field around a straight current carrying conductor or wire can be increased by bending the wire into circular loop. Right hand thumb rule is used to determine the direction of magnetic field produced due to current carrying circular wire.

Why magnetic field is created around a current carrying conductor?

MAGNETIC FIELD PATTERN DUE TO STRAIGHT CURRENT-CARRYING CONDUCTOR. Like stationary charges produce an electric field proportional to the magnitude of charge, moving charges produce magnetic fields proportional to the current. In other words, a current carrying conductor produces a magnetic field around it.

Where is the magnetic field due to a straight current carrying wire stronger or weaker?

In general, the magnetic field is strongest close to the wire and weaker farther away.

Which one decide the direction of magnetic lines of force due to a straight wire carrying current?

Rule used is-Right hand thumb rule’. (ii) Fleming’s left hand rule is used to find the direction of force experienced by a current carrying straight conductor, when placed in a magnetic field, which is perpendicular to it.

Why are magnetic field lines not straight?

There can’t be such straight field lines between magnetic poles as the magnetic field can always form closed loops. However the tangential vectors through each loops point in the same direction which is illustrated in the figure. Remember that the magnetic field is a pseudo-vector.

How do magnetic field lines bend in a circle?

(To visualise better , look up the images for magnetic field lines aroung a straight wire and around a current carrying loop ) . At the center of the circle ,every field line is at an equal distance , thus they exert equal pressure on each other ,and bend each other into the same direction.

What are the field lines around a current carrying wire?

The field lines around a current carrying wire are concentric circles. (To visualise better , look up the images for magnetic field lines aroung a straight wire and around a current carrying loop ) .

What happens to the magnetic field as we move away from wire?

Explanation: At every point of current carrying circular loop the concentric circles representing the magnetic field around it becomes larger and larger as we move away from the wire. At the centre of the loop the field appears as straight line. Should I hire remote software developers from Turing.com?

Why do magnetic field lines exist but not magnetic poles?

It actually just because of where you are observing from. Field lines are only a apparent (an illusion or magic trick) because they really don’t exist. A magnetic field is a “whole” and we use lines for convenience to visualize the field configurations and talk about them.
