compass
The small bar magnet has a stronger magnetic field, at least at short distances.
Well I don;t know the correct terms,but I think the distance is sometimes affect cause if the magnet is small the force would be as strong as you think but if the magnet is large the magnetism would be stronger than the small magnet of pulling together.
magnetic pull
Use a magnet. The iron will be attracted to the magnet but the lead won't.
Strap
because it is easy to convey from small bar magnet
small magnet used to give direction
A plotting compass is a small magnet which is suspended and is free to rotate. When it is near a magnet, the compass will always point in a particular direction (the north pole's direction) becasue of the force of the magnetic field.
A compass needle is a small magnet itself. When it is placed next to a larger magnet, the magnetic field of the larger magnet interacts with the magnetic field of the compass needle. This interaction causes the compass needle to align with the magnetic field of the larger magnet, causing it to spin and point in the direction of the magnetic field lines.

The small bar magnet has a stronger magnetic field, at least at short distances.
The space around a magnet where the force of the magnet can act is the space occupied by the magnetic field. Alternatively we say that the magnetic field acts in the space around a magnet. That is a very qualitative statement with little predictive value. More predictive value is contained in a statement that the strength of the magnetic field at any position in the vicinity of a magnet is measured by the torque which is exerted on a small magnet moment (compass) place in the vicinity of a magnet. This, recorded with the direction the test compass points is actually a mapping of the magnetic field of a magnet. As a side note, if carefully measured one discovers that strength of the field around a magnet decreases as the inverse cube of the distance when far from the magnet. The field is mostly in the volume near the magnet but the weakening field continues to exist at all distances from the magnet.
There is no (proven) danger,especially from a small magnet. If you had a large electro-magnet, maybe.
