The long solenoid S shown (in cross section) in Figure 9 has 220 turns/cm and carries a current I = 1.5 A; its diameter D is 3.2 cm. At its center we place a 130-turn closely packed coil C of diameter d = 2.1 cm. The current in the solenoid is reduced to zero at a steady rate in 25 ms. What is the magnitude of the emf that is induced in coil C while the current in the solenoid is changing?

Please just help with this question: What would be the terminal velocity of the rod if all the conditions of part (b) of the problem where held, except there was also friction with a kinetic coefficient of ?k=0.0215? (Note: I believe the answer for b) is the induced current of 0.049 A if it helps)
In figure below, the magnetig flux through the circular loop of radius r = 1.8 m increases according to the relation ΦB = 5 t2 + 5t + 3, where ΦB is in Webers and t is in seconds. What is the magnitude and direction (clockwise or counterclockwise) of the induced current in the circular loop at t = 1.5 s if the loop has a total resistance of R = 12 Ω? (Choose clockwise direction as the positive and express the direction of the current by using plus or minus signs in the result, which must be in units of Amperes and include 2 digit after the decimal point. That means if you get a result of 9.22 and the direction of the current is clockwise, just type 9.22 or if you find the direction of the current to be counterclockwise, just type -9.22 in the answer box. Maximum of 5% of error is accepted in your answer.)
Consider the rectangular loop in the figure below, which is fixed and under the influence of a uniform time-dependent magnetic field B (t). Show that the potential difference e (epsilon) induced in the loop is given by e = Acosθ db / dt, where A is the area of the loop.
The conducting rod shown in the accompanying figure moves along parallel metal rails that are 25-cm apart. The system is in a uniform magnetic field of strength 0.75 T, which is directed into the page. The resistances of the rod and the rails are negligible, but the section PQ has a resistance of 0.25 . (a) What is the emf (including its sense) induced in the rod when it is moving to tire right with a speed of 5.0 m/s? (b) What force is required to keep the rod moving at this speed? (c) What is the rate at which work is done by this force? (d) What is the power dissipated in the resistor?
A circular loop having a radius of R and having a current of current I was put in a uniform magnetic field with a strength of B and it is also pointing out of the page. An angle of 30° was made by the loop with respect to the positive x axis in such a way that the loop’s right hemisphere is above the xy-plane, whereas the left hemisphere is below. This is illustrated in the figure attached. From the choices, determine the loop’s potential energy and the magnitude of the torque it experiences.
A single turn coil of radius 4.50 cm is held in a vertical plane and a magnet is rapidly moved relative to the coil as shown in the diagram below. The field inside the coil changes from 0.315 T to 0.520 T in 0.120 s. If the resistance of the coil is 3.90 Ω, what is the magnitude and direction of the induced current in the coil as viewed from the side of the magnet? (a) magnitude (in mA) (b) direction
Shown is a 15-cm-long metal rod pulled along two frictionless, conducting rails at a constant speed of 3.5 m/s. The rails have negligible resistance, but the rod has a resistance of 0.65 Ω.a. What is the current induced in the rod?b. What force is required to keep the rod moving at a constant speed?
In the figure below, the conducting loop has fallen a short distance and is now falling at a constant velocity, vterminal. The loop has sides of length s=0.50 m, mass 30.0 g, and resistance R=1.00 Ω. If B=7.50 T and is directed into the page, answer the following question: What is the magnitude of the force pulling down on this loop and according to Lenz’s Law, in which direction will an induced current in the loop travel? Make sure to show how you know and all your work.
An inﬁnite solenoid with radius b has n turns per unit length. The current varies in time according to Iptq I0 cosωt (with positive deﬁned as shown in the ﬁgure, i.e., counterclockwise). A ring with radius r b and resistance R is centered on the solenoid’s axis, with its plane perpendicular to the axis.(a) What is the induced current in the ring? (b) A given little piece of the ring will feel a magnetic force. For what values of t is this force maximum? (c) What is the eﬀect of the force on the ring? In other words, does the force cause the ring to translate, spin, ﬂip over, stretch/ shrink, etc.?
A metal rod of mass m slides without friction along two parallel horizontal rails, separated by a distance ℓ and connected by a resistor R, as shown in the figure below. A uniform vertical magnetic field of magnitude B is applied perpendicular to the plane of the paper. The applied force shown in the figure acts only for a moment, to give the rod a speed v. In terms of m, ℓ, R, B, and v, find the distance the rod will then slide as it coasts to a stop. Note: See image for the original question and diagram.
A long, rectangular loop of width w, mass m, and resistance R is at rest, with the plane of the loop parallel to the ground. Immediately to the left of the loop is a region of uniform magnetic field B→ that points out of the screen. At time t=0, a constant force F→ pushes the loop to the left, into the magnetic field region, as shown in the figure. Derive an expression for the speed v of the loop immediately after it enters the magnetic field region in terms of the given variables and the time t.
