The magnetic coils of a tokamak fusion reactor are in the shape of a toroid having an inner radius of 0.700 m and an outer radius of 1.30 m. the toroid has 800 turns of large-diameter wire, each of which carries a current of 17.0 ka. (a) find the magnitude of the magnetic field inside the toroid along the inner radius. t (b) find the magnitude of the magnetic field inside the toroid along the outer radius. t

To solve this problem it is necessary to apply the concepts related to Magnetic field in a toroide.

By definition the magnetic field is defined as

Where,

Permeability constant in free Space

N = Number of loops

I = Current

r = Radius

PART A) For the internal radio,

PART B) For outside radio,

(a) 3.886 tesla  

(b) 2.09 tesla

Explanation:

inner radius, r = 0.7 m

outer radius, R = 1.3 m

current, i = 17 kA = 17000 A

Number of turns, N = 800

(a) The magnetic field is given by

B = 3.886 tesla

(b) The magnetic field is given by

B = 2.09 tesla

explanation:

a fuel engine ( known as a gasoline engine in american english )is an internal combustion engine with spark ignition, designed to run on petrol (gasoline) and similar volatile fuels.
