The magnetic field strength unto one

Key words: the magnetic field force electricity wire magnetic feeling line author: WuXingGuang

The force has two magnetic field: 1) we agreed, in any of the magnetic field a little, little CiZhen arctic stress direction, for the magnetic field that direction. Magnetic feeling in magnetic field lines are drawn some of the direction of curve, the curve in every bit of tangent direction and that the same direction of the magnetic field. Magnetic force direction is magnetic feeling the tangent of the line. For example the magnet's N level attract small magnets, small magnets magnetotactic line along the direction. Well the strong magnetic field, the magnetic force direction is a magnetotactic line direction. 2) vertical magnetic force direction are line. Two of the electricity of the wire, for example interact with each other.

I think two kind of force is in fact a kind of force, all is 2) vertical magnetic feeling in line ? direction

Magnetic field has the magnetic field with magnets, the magnetic fields generated electricity wires. Magnetic field interaction of magnets have magnets of interact with each other, to the role of electricity wires magnets, electricity to power the role of wire wires. Analysis, a bar magnet is have a clockwise and anticlockwise a magnetic field of magnetic field; The magnetic fields generated electricity wire is a clockwise or counterclockwise magnetic field magnetic field.

The role of power between wires, the same in current direction, wires near each other, and the current direction instead, wires away from each other. Vertical magnetic force direction are line direction. Analysis, the same in current direction (up), has counterclockwise magnetic field, the magnetic field. And the magnetic field near each other, on a wire of the left side, one on the right side of the wire, local magnetic feeling line in opposite directions, Clockwise vertical magnetic field lines are the direction of the force attract clockwise magnetic field. View analysis and experiment. Attracted to each other; Current direction instead, repel each other. Electricity wires of vertical magnetic effect between the line of the direction of force sense, repel each other or to attract each other. Small CiZhen in magnetic field can also be used in vertical direction of the magnetic feeling line force analysis. Vertical magnetic force analysis of the direction of feeling line bar magnet, a bar magnet is counterclockwise on both sides of the magnetic field to attract each other, a magnetic field clockwise and anticlockwise field repel each other, pole attracted to each other; Two levels of attracted to each other, such as N level attract S level, counterclockwise vertical magnetic field lines are the direction of the magnetic field strength attract counterclockwise。

So magnetic field on the magnetic field effect, it is vertical magnetic force direction are line interaction between a magnetotactic line direction not strong.

The direction of the magnetic force

With magnetic field are attracted to each other (chronological or counterclockwise with magnetic sense of direction), different magnetic field repel each other. Due to the different positions of the same magnetic field of magnetic field (or the opposite) and different magnetic field, turn it over to attract each other to be mutually exclusive, such as the same power between the wires, magnetic field force direction may be a magnetotactic line is the suction side, the other side is repulsion; Magnetic feeling around a circle line of line close together. Or no magnetic feeling line, but with a magnetotactic line vertical directions have a larger force line shut.

This wire by ampere force maximum, and magnetic field lines of force is the parallel.

Magnetic field force to a practical example

Small CiZhen in a magnetic field, belong to double magnetic field in the magnetic field phenomenon. Close to the magnetic field and magnetic field repels on one side, the other side also rejection; Close to the magnetic field and magnetic field attract on one side, the other side also attract. If a small CiZhen along the magnetic feeling line movement, belong to the result of joint action.

If you do not understand, the small CiZhen into electricity solenoid or ring current. Ring current by the joint action of ampere force, equal to the north and south pointing to CiZhen small, or to the poles movement. This shows the magnetic field strength only a, vertical magnetic force direction are line.

(using mathematical argument is even strength in a magnetic field, two small magnetic field of magnetic field CiZhen by two opposite direction of force, f1 = f2, force balance, CiZhen static; strong magnetic field in the well of imbalance, magnetic force along the direction to the magnetic field lines are, strong direction. A magnetotactic line direction of force is by force.)
