The magnetic field inside a solenoid is given by:B = µ₀nIwhere:B is the magnetic field in teslas (T)µ₀ is the permeability of free space (4π × 10−7 T⋅m/A)n is the number of turns per unit length (turns/m)I is the current in amperes (A)We are given that B = 2.50 T, n = 1000 turns/m, and we need to find I.Rearranging the equation above, we get:I = B/(µ₀n)Substituting the given values, we get:I = 2.50 T / (4π × 10−7 T⋅m/A × 1000 turns/m)I ≈ 1990 ATherefore, the required current is approximately 1990 A.
