4.15 A magnetic field of 100 G (1 G = 10–4 T) is required which is uniform in a region of linear dimension about 10 cm and area of cross-section about 10–3 m2. The maximum current-carrying capacity of a given coil of wire is 15 A and the number of turns per unit length that can be wound round a core is at most 1000 turns m–1. Suggest some appropriate design particulars of a solenoid for the required purpose. Assume the core is not ferromagnetic.

4.15 Magnetic field strength, B = 100 G = 100 10 - 4 T

Number of turns per unit length, n = 1000 turns / m

Current flowing in the coil, I = 15 A

μ 0 = Permeability of free space = 4 π * 10 - 7 T m A - 1

Magnetic field is given by the relation,

B = μ 0 n I or nI = B μ 0 = 100 * 10 - 4 4 π * 10 - 7 = 7957.75 A m - 1 8000 A m - 1

If the length of the coil is taken as 50 cm,
