Question

What kind of force field surrounds a stationary electric charge? What additional field surrounds it when it moves?
@Abhisar

Answer 1

there will be an electric field due to the charge, and a gravitational field due to the mass. a moving charge will also produce a magnetic field.

Answer 2

y?

Answer 3

i put due to whatever in there...
anyway, don't copy, and paste this answer. Put in your own words so that you can get the good grade ^-^

Answer 4

i don't copy and paste

Answer 5

When a charge is stationary then only electric field surrounds it. But when it starts moving an additional magnetic field surrounds it.

Answer 6

i get understanding so i can put in my own words

Answer 7

For the reason wait...brb

Answer 8

ohkay i am back

Answer 9

ohkay to know the xact reason for this u need to understand relativity theorem first !

Answer 10

To simply understand the phenomenon i'll tell u about Biot-Savart's Law which deals with the magnetic fied induction at a point due to small current

Answer 11

*Electromagnetism is not that simple it looks*

Answer 12

shall i ?

Answer 13

?????

Answer 14

sorry i'm here

Answer 15

proceed

Answer 16

Hmm..are u aquinted with Calculus ?

Answer 17

no

Answer 18

I don know how to xplain u then
O_o

Answer 19

try please let me see if i get it

Answer 20

Neither i am able to google anything which explains it simply

Answer 21

Biot savart's Law is an experimental law predicted by two pros named Biot and Savart.

Answer 22

Click the above link for the equation

Answer 23

i did

Answer 24

In it B is magnetic field intensity, i is current, dl is small length of conductor, r is distance between the point and conductor

Answer 25

ok i get that

Answer 26

Now using this equation we can calculate the amount of magnetic field a moving charge will exert. Since current is a kind of moving charge

Answer 27

ok

Answer 28

i'm back

Answer 29

got it ?
