Question

Magnetic field produced by current carrying coil depends upon the number of turns in the coil​

Answer 1

Answer:

$\huge \mathfrak \red{ \mid \bold{Answer}}$

▪︎The magnetic field strength of an electromagnet is therefore determined by the ampere turns of the coil with the more turns of wire in the coil the greater will be the strength of the magnetic field.

▪︎A wire coil that is carrying a current produces a magnetic field B( r), where r is the distance from the center of the coil to the field point. The strength of the field B is proportional to the current I in the coil. The strength and direction of the field depend on r. ... For large distances both fields fall off as 1/r3.
