The ampere rule of cooling fans
ampere rule in general it is expressed as the
1, the current of the magnetic field, with the right hand holding the conductor, let straight thumbs pointing in the direction of current a small mind by about four refers to a tidy mind has pointed out the direction is the direction of magnetic induction line around.
2, circular electric current magnetic field: let four fingers bend in his right hand and circular current in the same direction, the extended thumb is has pointed out the direction of the circular conductor is the direction of the magnetic induction on the spindle axis line ( Or extended thumb pointed out a ring current arctic 'N') Wenling city tong chi auto air conditioning manufacturing co. , LTD. , specializing in the production of cooling fans.
3, the magnetic field of screw pipe to power: with the right hand holding the screw tube, let the four fingers bend and done in the same direction current line, the extended thumb is the direction of the Buddha inside the solenoid in the direction of magnetic induction line ( Or referred to in the end is extended thumb screw tube 'N') of the arctic The morning high quality cooling fans
