In the figure, a 140-turn coil of radius 3.3 cm and resistance 6.9 Q is coaxial with a solenoid of 240 turns/cm and diameter 4.1 cm. The solenoid current drops from 1.7 A to zero in time interval At = 28 ms. What current is induced in amperes in the coil during At? Coil Solenoid Number i Units

Two coils of wire are placed close together. Initially, a current of 2.01 A exists in one of the coils, but there is no current in the other. The current is then switched off in a time of 2.58 x 102 s. During this time, the average emf induced in the other coil is 3.65 V. What is the mutual inductance of the two-coil system? Number i Units Switch Primary Secondary

In the figure, a 110-turn coil of radius 3.2 cm and resistance 7.7 Q is coaxial with a solenoid of 260 turns/cm and diameter 4.6 cm. The solenoid current drops from 2.1 A to zero in time interval At = 32 ms. What current is induced in amperes in the coil during At? Coil Solenoid Number i Units >

Question is attached with figure. Thanks

A square loop of wire of side a contains a resistor R and a capacitor C. The loop sits in a time-varying magnetic filed B = -Bot, Bo > 0. a) Find the maximum amount of charge on the capacitor. b) Find the magnitude and the direction of the induced current in the loop once the capacitor reaches its maximun charge. B R 0 Figure 4: RC circuit in a magnetic field

What is the CORRECT statement about Faraday's law of induction? a. The emf produced in a loop of wire is proportional to the magnetic flux b. The emf produced in a loop of wire is proportional to the time variation of the magnetic flux c. The emf produced in a loop of wire is proportional to the magnetic flux density times the loop's area d. The emf produced in a loop of wire is proportional to the current divided by time

I need a clear explanation please

A conducting bar sits on top of two parallel rails. A uniform magnetic field B is steady and directed to the right. The bar moves upward with velocity v. What is the polarity of the induced emf in terminals X and Y? X Y O X and Y are at the same potential. X is positive and Y is negative. O Y is positive and X is negative. 1-1

Your answer is partially correct. In the figure, a 100-turn coil of radius 3.0 cm and resistance 5.0 Q is coaxial with a solenoid of 200 turns/cm and diameter 4.0 cm. The solenoid current drops from 1.7 A to zero in time interval At = 21 ms. What current is induced in amperes in the coil during At? Coil Solenoid ▬▬▬▬▬ Number i 0.127 A Units

after switch S is closed at timet= 0, the emf of the source is automatically adjusted to maintain a constant current i through S. a) b) Find the current through the inductor as a function of time. At what time is the current through the resistor equal to the current through the inductor? Constant current R source ell
