Having quite a bit of trouble understand which formula's to use for these questions. Can you please help me?
Here is the questions
______________________________________________________________________________
Q.2. Calculate how many turns of wire must be wrapped around a hollow, non-magnetic (air) core 2 cm in diameter and 10 cm in length in order to create an inductance of 22mH. You may use the permeability of free space (μ0) for the μ value of the air core.
____________________________________________________________________________
Q.3. Next, calculate the required number of turns to produce the same inductance with a solid iron core of the same dimensions, assuming that the iron has a relative permeability (μr) of 4000.

Magnetic Circuits y Part A - Calculate reluctances Learning Goal: To understand how magnetic structures can be analyzed by drawing an equivalent circuit, and to use the equivalent circuit to calculate magnetic fluxes and coll currents. When analyzing magnetic structures, the geometry is often complex enough that using the fundamental rules can be very difficult without numerical methods. However, there are approximate methods that are often sufficient for engineering calculations. When the magnetic field is mostly contained within cores of...
