The reason of magnetic force:

1, permanent magnet

2. electromagnetism

If a straight metal wire is electrified, a circular magnetic field will be generated in the space around the metal wire. The greater the current flowing through the wire, the stronger the magnetic field. The magnetic field is circular and surrounds the wire. The direction of the magnetic field can be determined according to the "right hand rule": extend the thumb of the right hand and bend the other four fingers to the palm of your hand together. At this time, the direction of thumb is the direction of current, and the direction of other four fingers is the direction of magnetic field. In fact, the magnetic field generated by this straight wire is similar to the effect of placing a circle of small magnets with NS poles connected end to end around the wire. If a long metal wire is wound around a hollow cylinder in one direction, the resulting object is called a solenoid. What will happen if this solenoid is energized? When the solenoid is energized, it will generate a magnetic field every turn, and the direction of the magnetic field is indicated by a circular arrow. Then, at the position between two adjacent turns, because the magnetic fields are in opposite directions, the total magnetic field cancels; Inside and outside the solenoid, the magnetic fields generated by each turn of the coil are superimposed on each other, and finally the magnetic field shape is formed. It can also be seen that the shape of the magnetic field outside the solenoid is the same as that generated by the magnet. The magnetic field inside the solenoid just forms a closed magnetic field line with the external magnetic field. The solenoid is represented by two rows of circles, as if the solenoid were cut from the middle. There is a cross on the top row, indicating that the current flows out of the screen; There is a black dot in the lower row, indicating that the current flows from the outside of the screen to the inside.

3. Flowing liquid metal. The causes of magnetic force are not just permanent magnets and electromagnetism. Scientists have found that flowing metal can produce a strong magnetic field. Some scientists have done experiments: pouring molten iron into a sphere and making the sphere rotate, thus generating a huge magnetic force. Based on this, it is speculated that there may be a liquid iron core in the earth, which keeps rotating, thus forming a magnetic field. It also found the basis for the change of the earth's magnetic field intensity and even the exchange in the history of the north and south poles.
