Asolenoid with n turns per unit length has radius a. it is connected to a power supply that drives a current increasing linearly with time as i(t) = ct, where c is a constant. assume the magnetic field is uniform inside the solenoid. find an expression for the magnetic field inside the solenoid as a function of time, and determine the magnitude of the induced electric field just inside the solenoid. (use the following as necessary: a, n, t, c, and mu_0. do not substitute numerical values; use variables only.) b(t) = |e| = what is the magnitude of the electric field induced just inside a solenoid that has exactly 11 turns/cm and a radius of 2.1 cm if the current increases at a rate of 0.70 a/s? n/c

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
