i was woundering because im trying to experiment witha metal and contain it with another metal 2 resist the N of gravity
of course u can increase magnetic field flux density by electricity. Wind a metal of having good magnetic properties with a coil, when current flows through that coil magnetic flux is generated. But there is a B-H curve, it tell about characteristics of magnetic material with current. it shows that with increase in current, magnetic flux density increases. but, after certain value of current, material gets saturated (called knee point). After knee point, rate of increase in flux density decreases with current and finally it reaches to zero also. But there is a way still to increase flux. for that u have to increase size of the magnetic material. the more the material and current. the more magnetic field u can get
