Question

Consider a circular coil of wire consisting of 200
turns, each of radius 10 * 10-2 m, carrying a
current of 0.2 A.
What is the magnitude of the magnetic field at the
center of the coil?​

Answer 1

Explanation:

A renewable resource is a natural resource which will replenish to replace the portion depleted by usage and consumption, either through natural reproduction or other recurring processes in a finite amount of time in a human time scale.

Answer 2

Answer:

2.51*10^-4T

Explanation:

no.of turns on the circular coil,n=200

radius of each turn,r=10* 10-2m

current flowing in the coil,I=0.2A

|B|=μo2πnI/4πr

= 4π*10-7*2π*209*0.2/4π*10*10-2

=2.51*10-4T
