Answer 1

Answer:

of radius 3m, is placed in yz plane. it carries current, of 4a, directed from y axis to z axis.Circular coil, compass box, ammeter, rheostat, commutator, cell, key, ... A current carrying wire generates a magnetic field. According ... At the centre of the coil, the field will be calculate the magnetic induction at its - 14256

Answer 2

$B=8.38\times 10^{-7}$T

Explanation:

Radius of coil,r=3 m

Current in coil=I=4A

Magnetic induction at center of coil,B=$\frac{\mu_0 I}{2r}$

Where $\mu_0=4\pi\times 10^{-7}Tm/A$

r=Radius of coil

I=Current in coil

Substitute the values then we get

$B=\frac{4\times \frac{22}{7}\times 10^{-7}\times 4}{2(3)}$

Where $\pi=\frac{22}{7}$

$B=8.38\times 10^{-7}$T

The direction of magnetic field is perpendicular to the plane o coil and it is directed inward.

When we find magnetic induction at center of coil then the magnetic induction has no no vector form.
