Thales of Miletus, a Greek philosopher, discovered that rubbing amber with silk created an electric charge in the amber which caused objects to be attracted to it. If rubbed enough, it created a spark, much like we receive when we walk on carpet and touch a doorknob and see, hear and feel the spark.

∙ 13y agoIt comes from the Greek word "electron." However, to the Greeks that word didn't mean what it does to us; it meant the material we call amber. It's called that because one of the first noticed electrical phenomena was that if you rubbed a piece of amber with a cloth you could build up a static charge and make a small spark.
compound word for cloth
in medieval times a standard bolt of cloth was 40 cloth-yards (37 inches) in length
What us a word to mack cloth to make a compound word
One sq yd of cloth has 1296 square inches in it
it created an electrical charge
A philosopher named Thales discovered it when he rubbed a cloth on a hard-fossilized material called Amber it would pick the straw in his barn up.
Thales discovered static electricity by rubbing a peice of amber against a silk cloth.
when amber is rubbed with silk cloth +ve charge comes on silk cloth and -ve on amber due to interaction between their molecules, so is that when we comb our hairs , then -ve charge comes on comb and +ve on hairs,so when we bring silk cloth near the comb they attract each other due to 'ving opposite charges
The Greeks first wrote about static electricity generation. A silk cloth rubbed on an amber rod.
over 2500 years ago when they rubbed amber with cloth it attracted small objects
the sand would stand up
A plastic ruler is rubbed vigorously with a woolen cloth
Silk Cloth
The Greeks used the amber to study the concept of magnetism for the first time . They observed that it acquires a strange property of attracting tiny bits of papers,metal pieces etc. when rubbed with a piece of wool .this strange characteristic of it made the further discoveries possible.+++That's not magnetism but static electricity, the charge being developed by rubbing the amber with the dry cloth. Amber is non-magnetic.
Thales of miletus (an ancient greek city) experimented with electromagnetics and in that way created what today we know as static electricity. He waved a rod over a cloth with thingees on it and created electromagnetics.
When glass rod is rubbed with silk cloth it becomes positively charged and the silk cloth becomes negatively charged. This is because the glass rod looses electrons to the silk cloth which makes it positive and the silk cloth becomes negative.
