The beneficial powers of Rudraksha are by virtue of its Electrical and Magnetic Properties.  

Electrical Properties -The ability to send out subtle electrical impulses & Inductive vibrations and act as a Dielectric as in a capacitor to store electrical energy.

Our Human body, The Central Nervous System, Autonomous, Sympathetic & Para sympathetic Nervous System and Various other Organ systems in to can be considered a complex Bio Electronic circuit.

Constant pumping of blood by the heart, blood circulation, the transmission of various impulses -Touch, Noise, Smell, Sight, Taste to the brain and the continuous movement of Neurons and Neurotransmitters in the brain and Nervous system generates electrical impulses. This is termed as Bioelectricity. This flow of Bioelectricity facilitates movement of information from the brain to various parts of the body and back. What we feel, think, hear, taste, see. Perceive all depends on the subtle flow of Bioelectric current. This flow of Bioelectric current is occurs due to the existence of potential differences or the different energy levels between different parts of the body.

As long as the flow of Bioelectricity is smooth the body functions normally and we have the feeling of being in control.

But there is a third element to the Body and Brain Bio Electronic circuit Interface, that of the mind. Any activity that can produce stress or maladjustment can throw the streamlined activity, the Electronic circuit of the Body& Mind out of gear. Human beings and all living beings are prone to stress continuously in the continuous fight for survival and prosperity.

In modern age with intense competition the Stress levels have increased tremendously. Almost every individual has problems of Stress and Stress related ailments like insomnia, alcoholism, depression, Maladjustments, heart diseases, skin diseases etc. Any Doctor will confirm that almost 95% of the ailments are Psychosomatic or Stress related (i.e.) originating from Mind. When there is Stress or Maladjustment corresponding Stress signals are sent to the Central Nervous systems, there is an increased activity or abnormal of Neurons and Neuro transmitters. The magnitude of change will depend on the cause and specific case.  When such a thing occurs and it occurs continuously, streamlined flow of electrical signals throughout the Mind-Body interface is disrupted and it makes us feel uncomfortable and we are not able to act with our full efficiency. Our Blood circulation becomes Non-ideal and we feel various illnesses. Unfortunately this happens all the time.

Rudraksha beads act as a Stabilizing Anchor. Rudraksha beads' electrical property can be broadly categorized into  

1) Resistance- There is continuous and subtle flow of bioelectrical signal throughout the body due to potential difference between parts of the Body. Rudraksha beads of particular Mukhis or Facets have a definitive Factor of Resistance. It is measured in Ohms. When these beads resist the flow of bioelectrical impulses a specific ampere of current flow is generated depending on the factor of resistance. This acts in tandem with heartbeat, streamlining it and sending out specific impulses to brain. These impulses stimulate certain positive brain chemicals. Making us feel better, more  confidants, poised and more energetic. It has been observed that specific Mukhis or Facets of Rudraksha beads send out specific signals acting on a particular brain chemical and thereby by effecting specific positive changes in personality. It is well proven that the state of mind and our personality is governed almost completely by the Brain, it’s functioning and that of Central Nervous System  

2) Capacitance or the Dielectric Properties -Rudraksha beads act as dielectric (i.e.) as a storage of electrical energy. This property of Rudraksha makes it capable in stabilizing and anchoring the Bioelectric current. The values are measured in units of Farad. This property is very helpful in controlling hyperactivity, palpitations of heart, streamlining heartbeat etc. Due to stress when there is increased physical activity heart beats faster and the overall activity of hormones and nervous system increases. This causes increased energy levels or increase in potential difference. As a result of this the magnitude of the Bioelectric Current increases. Rudraksha beads acting as Dielectric store this excess Bioelectric Energy , thereby streamlining the overall activity to Normalcy.  

3) Inductance -Rudraksha beads by it have permanent magnetic properties. They have been observed to send out Inductive vibrations with frequencies measured in units of Henry (Volt Seconds/Ampere). This perhaps  is the reason why people have felt better even when Rudraksha beads does not touch them physically.

Magnetic Properties -Rudraksha beads have Both Paramagnetic and Diamagnetic with the most important property of Dynamic Polarity We all are most probably aware of the beneficial healing properties of magnets. Magnetic Healing is becoming extremely popular off late and everyone who have been using magnets for healing have been getting the benefits and found overall betterment and rejuvenation. Rudraksha beads retain most of the properties of Magnets but it is unparallel in one aspect, that of the ability to change it's polarity or the Property of Dynamic Polarity.  The basic way of healing is based on the fact that the when the passage of arteries and veins which carry blood to and from Heart to all the parts of the body is blocked or reduced due to variety of reasons, various illnesses creep. Blood carries oxygen and energy to various parts of the body and cleanses it off waste materials.  Any disruption of the smooth flow of Blood circulation is bound to cause illnesses.

We experience pain and uneasiness due to improper blood circulation. Every cell in the blood as well as the Arteries and veins are charged either positively or negatively. Magnets have the poles Positive (+) and Negative (-).

When magnets are passed on various parts of the body the opposite poles of the magnets and that of cells get attracted and there is an expansion of the passage .The Arteries and veins open up to facilitate streamlined blood circulation. When there is a streamlining of blood circulation most of the illnesses get automatically healed and we feel better and rejuvenated.

But with magnets the polarity is fixed. When magnets are brought near a particular part of the body it opens up only those sections of veins and arteries where there is a matching of polarities hence complete healing and streamlining of blood circulation cannot be ensured. We experience healing and feel better but we can still go much further with Dynamic Polarity of Rudraksha beads.

Rudraksha has the ability to Change it's polarity-The property of Dynamic Polarity. This in turn is by virtue of its property, Diamagnetism. Diamagnetism is termed as the ability of any material to acquire temporary magnetic property in presence of an external magnetic field. The polarity of the charge induced is opposite to that of the external field inducing the charge. Blood circulation and heart beat automatically induces a magnetic field around the body and particularly the heart Region. Bioelectricity automatically gives raise to Biomagnetism Depending on the polarity of the Induced magnetic field. Rudraksha bead acquires a polarity that is opposite of the inducing field. As a result of this the opening up the passages of Arteries and Veins are far better than that of magnets. Much better healing and rejuvenation is experienced.

Various Literatures mention of powerful Anti Ageing properties of Rudraksha beads

This is mainly because of the Dynamic Polarity of the Rudraksha a bead thus the healing powers of Rudraksha are far superior to that of Magnets. In some sense Rudraksha beads can be termed to have some additional life or Intelligence as against Magnets.
