At A magnetic field of 37.2T, the current needed to achieve such a field i = 3.72 * 10⁶ and i = 2.49 * 10⁵ A

A magnetic field is a vector discipline that describes the magnetic effect on shifting electric-powered charges, electric currents, and magnetic materials. A moving price in a magnetic subject reviews a pressure perpendicular to its own speed and to the magnetic discipline

Given,

Magnetic field = 37.2T

i) 2.00 cm from a long, straight wire.

B = μ₀i/2πl

i = B2πl /μ₀

i = (37.2)2π(0.02)/4π * 10⁻⁷

i = 3.72 * 10⁶

ii) At the center of a circular coil of radius 42.0cm that has 100 turns.

B = μ₀Ni/2r

i = B2r/μ₀N

i = (37.2)2(0.42)/4π * 10⁻⁷*100

i = 2.49 * 10⁵ A
