A solenoid is required to produce a magnetic field at its center of magnitude B = 15 T. It is to have length L = 2 m, bore radius a = 10 cm, and can be approximated as an infinitely long object. It is to be constructed of 10,000 turns of superconducting wire. What current must the wire carry to produce the desired field?

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
