what's the point of magnetic field
Answers
Answer:
The properties of magnetic field lines can be summarized by these rules: The direction of the magnetic field is tangent to the field line at any point in space. A small compass will point in the direction of the field line. The strength of the field is proportional to the closeness of the lines.
Explanation:
As Ampere suggested, a magnetic field is produced whenever an electrical charge is in motion. The spinning and orbiting of the nucleus of an atom produces a magnetic field as does electrical current flowing through a wire. The direction of the spin and orbit determine the direction of the magnetic field.
- They seek the path of least resistance between opposite magnetic poles. ...
- They never cross one another.
- They all have the same strength.

Explanation:
Magnetic fields surround and are created by magnetized material and by moving electric charges (currents) such as those used in electromagnets. They exert forces on nearby moving electrical charges and torques on nearby magnets.
