To get an idea of the order of magnitude of inductance, calculate the self-inductance in henries for a solenoid with 900 loops of wire wound on a rod 6 cm long with radius 1 cm?

The  self-inductance is  

Explanation:

From the question we are told that  

      The number of loops is  

      The  length of the rod is  

      The radius of the rod is  

The  self-inductance for the solenoid is mathematically represented as

Now the cross-sectional of the solenoid is mathematically evaluated as

substituting values  

and   is the permeability of free space with a value  

    substituting values into above equation

false

explanation:

boats, things on boats luggage are way more heavy then water.
