Question

A toroidal solenoid has a central radius of 0.50 m and a cross-sectional diameter of 10 cm. When a current passes through the coil of the solenoid, the magnetic field inside the solenoid at its CENTER has a magnitude of 2.0 μT. What is the largest value of the magnetic field inside the solenoid when this current is flowing? (μ0 = 4π × 10^−7 T • m/A)

a. 1.8 micro T
b. 0.50 micro T
c. 2.8 micro T
d. 2.2 micro T
e. 3.5 micro T

1. To solve this problem we will apply the concepts related to the magnetic field. From the magnetic field we will compare what happens with the distance or the radius between the bodies and we will make the replacement with the values we have. The largest value of magnetic field,

Here,

= Permeability at free space

N = Number of loops

I = Current
