NEED HELP PLEASE: Estimate the inductance L of a coil that is 12 cm long, made of about 250 copper-wire turns and a diameter of about 0.75 cm. Re-estimate the inductance with an iron core inserted in this coil. Show work and units. This question teaches you that, as with the resistance and the capacitance, the inductance is also a GEOMETRICAL property.
After you measure the self-inductance of a coil, you unwind it and then rewind one third the length of the wire into a coil with the same diameter and third length and with half the number of turns. How does this change the self-inductance? L = μ₀n^(2)AI Please show me how the final equation comes about.
constant voltage source R W 2000 Coil represented by pure inductance and internal resistance L c* variable capacitor + Figure 10.1: Circuit for the LRC series resonance. The inductor in the circuit is a coil made of 1500 turns of copper wire. 1. Assume you have a coil made of a single loop of wire of radius, r, carrying a current, I. Find an expression for the magnetic field, B, at the centre of the loop. 2. If you now...
Find the self-inductance of a solenoid 70 cm long and 5.8 cm in diameter that contains 2000 turns of wire.
A solenoid 10.0 cm in diameter and 77.0 cm long is made from copper wire of diameter 0.100 cm, with very thin insulation. The wire is wound onto a cardboard tube in a single layer, with adjacent turns touching each other. What power must be delivered to the solenoid if it is to produce a field of 7.80 mT at its center? The answer is in W.
A solenoid 10.0 cm in diameter and 82.7 cm long is made from copper wire of diameter 0.100 cm, with very thin insulation. The wire is wound onto a cardboard tube in a single layer, with adjacent turns touching each other. What power must be delivered to the solenoid if it is to produce a field of 8.35 mT at its center? (Assume the resistivity of the copper wire is 1.70 ✕ 10−8 Ω · m.)

The standard equation used by Hams and engineers to calculate the inductance of a solenoid coil is Wheeler’s formula (1928). It is L=(a^2 n^2)/(2.54×(9a+10b)) , where L is the inductance in microhenry, a is the coil radius in cm, and b is the coil length in cm and n is the total number of turns. We are now designing a solenoid coil for a solid-state NMR probe, aiming at a coil of 0.05 microhenry as the inductance. Please notice that...
