magnetic field is produced around it
. The field lines are in the form of concentric circles at every point of the current-carrying conductor.
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.
What is the magnetic field of a circle?
Summary. The magnetic field strength at the center of a circular loop is given by
B=μ0I2R
(at center of loop), B = μ 0 I 2 R (at center of loop) , where R is the radius of the loop. RHR-2 gives the direction of the field about the loop.

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.
What is direction of magnetic field lines?
The lines are directed from
north pole to the south pole outside the magnet
while they are directed from south pole to north pole inside the magnet. A tangent drawn on a magnetic field line gives the direction of the magnetic field at that point.
Why is magnetic field circular?
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 curved and not straight?
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.
The interactions between electric currents and magnetic fields create forces. The magnetic force on a current in a magnetic field
= current x displacement across the magnetic field
. … When two currents are directed through magnetic fields in the same direction, they attract.

= qvB to be composed of (Newton x second)/(Coulomb x meter). … A smaller magnetic field unit is the Gauss (1 Tesla = 10,000 Gauss).
Where is the magnetic field due to current through a circular loop uniform?
Magnetic field due to current through circular loop is uniform
at the centre of the current loop
and non-uniform near the circular coil.
How will the magnetic field produced at a point due to a current carrying straight conductor change if we I increase the current flowing through the conductor?
When we increase the distance from the coil, the magnetic field produced by a current carrying circular coil
decreases
. … So if we increase the number of turns of the coil, more current will pass through the wire which indicates that the magnetic field associated with it also increases.
Which rule gives the direction of magnetic field around a straight conductor?

Does a current carrying circular coil produce uniform magnetic field?
No, magnetic field produced due to a current carrying cirular coil
is not uniform
. However, it may be considered as uniform at the centre of the coil.
Why magnetic field lines are curved at the edges?
It is
due to fringing of electric field lines near edges of the electrodes
. You can solve for the potential distribution in region around the electrodes by using a numerical code that solves the Laplace equation for voltage, with the electrodes as equipotentials of some fixed values as boundary conditions.
Is magnetic field directly proportional to current?
Experimentally, it is found that the magnitude B of the magnetic field produced by a long,
straight wire is directly proportional to the current I
and inversely proportional to the radial distance r from the wire as shown below.
Do magnetic field lines form closed loops?
Magnetic field-lines
form closed loops which never begin or end
. Thus, magnetic field-lines behave in a quite different manner to electric field-lines, which begin on positive charges, end on negative charges, and never form closed loops.
Why are magnetic field lines always curved?
Magnetic field lines are closed curve
because for a magnet there are no monopoles i.e., a magnet always has two poles
(north pole and south pole) even if it is cut from anywhere between. … Therefore, magnetic field lines always form closed loops.
Are magnetic fields curved?
Magnetic field lines
do not like to bend
, so when the space around them becomes warped by large masses, the fields fight back. Magnetic field lines do not like to bend.
