Option E
Because, energy = 1/2 L i ^2
Since energy is square of current and hence current of solenoid A is three times of B thats why energy of A is 9 times of B.
Add Answer to:
times 3. Two identical solenoids, A and B, carry currents where IA = 316. Therefore, solenoid A contains the energy of...

Imagine that we have two solenoids. Solenoid 1 has Nį loops, a length li, and a radius ai, while solenoid 2 has N2 loops, a length l2, and a radius a2. Assume that l2 <lı and a2 > a1. The solenoids are arranged as shown (here we just show the cross-section in the page, but both consist of full, circular loops). For parts a-d, treat the solenoids as ideal. a.

An ideal solenoid generates a uniform magnetic field inside the solenoid. Here we place two long ideal solenoids as shown (with radii 40 mm and 20 mm, respectively). The current carried by the outer solenoid It is three times as large as the current carried by the inner solenoid I2. In order to make the magnetic field inside the inner solenoid zero, what should be the ratio of the number of turns per unit length for the...

3R MC 12 Two identical solenoids are connected to each other so that they carry the same current, and are inserted through two loops in an electrical circuit, as shown left diagram. The solenoids are oriented such that when you loolk from one end, the currents are circulating in opposite directions, as showin in the second diagram. For a period of time, the current flowing through the solenoids is changing in a steady linear manner: It) ~ t. During this...

3. (a) Ampère's law can be written in the following form: $6.d1= B.d = Hol. Use this to show that the magnetic field B inside a toroidal-shaped solenoid, with n turns per unit length and carrying a current I, has a magnitude equal to Monl. Explain how you result can be used to obtain the magnetic field inside a long straight solenoid, with n turns per unit length. {4} (b) Faraday's law can be written in the following form: $...
