What two factors does the strength of a magnetic field depend on? what about an electric field?

The answer is the quality of attractive field relies on Electric current, change in time of electric field and attractive penetrability and a district around a charged molecule inside which power can be applied on other charged molecule.  

Explanation:

The attractive field is the zone around a magnet in which there is an attractive power. Moving electric charges can make attractive fields. In material science, the attractive field is a field that goes through space and which makes an attractive power move electric charges and attractive dipoles. The Coriolis drive, coming about because of the Earth's turn, likewise causes twirling whirlpools. This stream of fluid iron creates electric ebbs and flows, which thus deliver attractive fields. Charged metals going through these fields proceed to make electric streams of their own, thus the cycle proceeds.
