A substance that is magnetism sensitive will experience a magnetic force from an invisible field called the magnetic field.Magnetic field lines do not cross each other. Magnetic field lines always make closed-loops. The magnetic field lines always begin from the north pole and terminate at the south pole. The density of the field lines denotes the strength of the field.Magnetic field lines of a long straight wire:
The magnetic field lines of a long straight wire are comprised of concentric circles centered around the wire. The direction of magnetic field lines is given by the right-hand thumb rule. An illustrative diagram of magnetic field lines of a long straight wire:
therefore, from the above information of magnetic field lines of a long straight wire, option D is correct.

Magnetic field lines never intersect each other because
There will be two directions of the field at the same point.
Feild lines repel each other
Field lines follow discrete paths only
If field lines intersect they create a new magnetic field within the existing fieldTwo parallel wires carry currents of 20 A and 40 A in opposite directions. Another wire carrying a current antiparallel to 20 A is placed midway between the two wires. The magnetic force on it will be
