In Electro homoeopathy, an electrified medicine used as externals is based on the law of polarity.

Polarities in Electro homoeopathy explain minute electric charges of human body.

The law of polarity was first demonstrated by Dr.charazain & m.decle in 1886.

There are two charges [positive, negative] balanced equally in our body.

Right half of the body, face, and trunk: feet: palm has negative charges.

Left half of the body face and trunk has positive charges.

Inner part contains negative whereas outer part contains positive charges.

In mid line of body from top of the head to pubis,there is alternatively positive & negative charges.[Neutral]

If any disease appear in the body, it will alter the charges.

If positive pole of magnet apply over positive part of body produces contraction of muscles.

If negative pole of magnet apply over negative part of body produces contraction of muscles.

If apply negative pole magnet to positive part or positive pole magnet to negative part produces relaxation of muscles.

Absolutely the same phenomenon is produced by application of electricity medicines.
