How Does The Strength Of The Magnetic Field At The Centre Of The Coil Depends On?

How Does The Strength Of The Magnetic Field At The Centre Of The Coil Depends On? 1) if the radius increases the magnetic field lines go farther and farther so the strength of the magnet decrease. 2) if the number of turns increase then the magnetic field lines become denser. So the strength of the

What Is The Relationship Between Distance And Strength In Both Electric And Magnetic Fields? If the distance between two magnets is doubled the magnetic force between them will fall to a quarter of the initial value. If the distance between two magnets is halved the magnetic force between them will increase to four times the
