Question

How does the strength of magnetic field at centre of current carrying circular coil depends on the I) the radius of the coil Ii)number of the turns in the coil Iii)strength of the current flowing in the coil Please and fast no links no links no links and fully ASAP.... Please

Answer 1

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 magnet increase.
3) if the flowing in the circuit increases then the number of the magnetic field lines increased so strength of the magnet increase.
