The deflection of the compass needle decreases as the distance from the current-carrying wire increases, indicating a diminishing magnetic field influence with greater distance.

The magnetic field produced by a current-carrying straight wire decreases as the distance from the wire increases, as illustrated by the concentric circles becoming larger in the figure.

When the compass is moved away from the copper wire while maintaining the same current, the deflection in the needle decreases.

An increase in current results in an increase in the magnitude of the magnetic field produced at a given point.

The deflection of the compass needle increases as the current in the copper wire is increased.

Magnetic field lines do not cross each other because, at the point of intersection, the compass needle would have to point towards two directions simultaneously, which is not possible.

The relative strength of the magnetic field is indicated by the degree of closeness of the field lines. A stronger magnetic field is associated with crowded field lines.

Inside a magnet, the direction of magnetic field lines is from its south pole to its north pole, forming closed curves.

The direction of the magnetic field is determined by the direction in which a north pole of a compass needle moves inside it. Conventionally, it is established that magnetic field lines emerge from the north pole and merge at the ...

Yes, magnetic field lines around a bar magnet can be obtained by drawing them. It is possible to manually represent the magnetic field lines through observation and illustration.
