Which of the following statements are characteristics of magnetic fields? Select all that apply.
Magnetic fields point from the north pole to the south pole of a magnet.
The earth's magnetic field has no effect on the electron rays coming from the sun.
An example of the Biot-Savart law is the effect of the earth's maghytic field on the electron rays coming from the sun.
The north pole of a magnet will be attracted to the south pole of the earth.
If a bar magnet is cut in half two magnets with like poles will be created.

Magnetic fields point from the north pole to the south pole of a magnet.

The north pole of a magnet will be attracted to the south pole of the earth.

If a bar magnet is cut in half two magnets with like poles will be created

Explanation:

The magnetic field of Earth is due to the presence of iron in the core of the Earth.  

The metal emits the magnetic waves from it and the North and South pole of the planet.

Both the poles emit the magnetic rays which create magnetic sheet around it. The Earth acts like a magnet bar if which is cut into two half, the planet will act like two magnets. Also, Biot Savarts's law states that the magnetic field does not affect the electron rays coming from the Sun.

Thus, the selected options are correct.
