Answer 2

Answer:

Magnetic fields must start at the north pole of a magnet and end at the south pole of the magnet.

Explanation:

The lines that shows the direction of electric and magnetic field are called electric and magnetic field lines.The direction of electric field is from positive charge to negative charge.

The magnetic filed lines start at the north pole of a magnet and end at the south pole of the magnet.

Hence, the correct option is (2) "Magnetic fields must start at the north pole of a magnet and end at the south pole of the magnet".
