An electrical field is the core driving force for any electronic component. It is defined as the
electric force per unit charge and it radiates outward from the positive charged particle
towards the negative charged particle as shown below
Figure 1 Electric field lines
The region where the field lines occupy is the one termed as the electric field. This field is
utilized in many electronics and power generation schemes. An example of application of
electric field is on electronic doors, bells and loudspeakers. Consider an electromagnet that is
used in all of the above gadgets it functions according to the principle explained below.
An electromagnet is made of a soft metal that becomes magnetic when a current passes
through it. The faster it gains the magnetism the faster it losses it again. This principle is
utilized in the electronic bells and door locks.
When the electromotive force passes from the battery, it induces an electric field around the
coil and it turn a magnetic field is induced in the iron core according Faraday’s first law of
Electricity. This ability to gain and lose magnetism easily makes it useful in making contact
and losing contact in electronic bells and door locks. It is evident that no electronic gadget
can work effectively without a driving force.
