A solenoid is wound with a single layer of insulated copper wire (of diameter 2.8 mm) and is 2.2 cm in diameter and 0.6 m long. How many turns are on the solenoid? Assume that adjacent wires touch and that the insulation thickness is negligible. Submit Answer Tries 0/10 What is the inductance per meter for the solenoid near its center? Submit Answer Tries 0/10

A long solenoid with 10 turns per centimeter is placed inside a copper ring such that both objects hove the same central axis. The radius of the ring is 10.0 cm. and the radius of the solenoid is 5.0 cm. (a) What is the emf induced in the ring when the current 2 through the solenoid is 5.0 A and changing at a rate of 100 A/s? (b) What is the emf induced in the ring when 1=2.0A and. dI/dt=100A/s ? (c) What is the electric field inside the ring for these two cases? id: Suppose the ring is moved so that its central axis and the central axis of the solenoid are still parallel but no longer coincide. (You should assume that the solenoid is still inside die ring.) New what is the emf induced in the ring? (el Can you calculate the electric field in die ring as you did in part (c)?

An air-filled cylindrical inductor has 2600 turns, and it is 2.4 cm in diameter and 34.5 cm long. What is its inductance? How many turns would you need to generate the same inductance if the core were iron-filled instead? Assume the magnetic permeability of iron is about 1200 times that of free space.

What is the self-inductance (in mH) of a solenoid 31.6 cm long having 397 turns of wire and a cross- sectional diameter of 14.7 cm? mH

Can someone please explain it to me ASAP??!!!

bat i R= The circuit shown in the figure contains a resistor and a solenoid. A battery is connected by closing the switch in the figure and provides an EMF Vbat = 15 V. At a time t = 50 ms after the switch is closed the current in the circuit reaches a value of 1.0 A which corresponds to 25 % of its steady state value. What are the values of the resistance and inductance? Provide your answer to two significant figures. R 2 L = x² H
