Magnetic Field and Field Lines

A magnet will align in South-North direction when there is no separate magnetic field present.

The end of the magnetic needle pointing the South side will be its north pole.

How will a magnet align if there is no magnetic field present? Which pole will be aligning towards the South side?

Two magnetic field lines can never ever intersect.

An electric field has a direction, but a magnetic field does not.

The SI unit of magnetic field induction is _________.
