Asuperconducting solenoid is to be designed to generate a magnetic field of 10 t if the solenoid winding has 2000 turns meter what is the required current

3981 A

Explanation:

B = 10 t

n = 2000 per metre

Let the current is i

Use the formula for the magnetic field due to a current carrying solenoid

B = μo n i

10 = 4 x 3.14 x 10^-7 x 2000 x i

i = 3980.9 A = 3981 A

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
