Answer #1

Solution:

Length of solenoid = 5 m

Current flowing I = 1.5 A

Magnetic induction or magnetic flux density = B

we need to find the number of turns of the solenoid ?.

We know    

where N is the number of turns.

is the permeability of free space = 4π x 10-7

therefore

  

Number of turns N = 10

b) what is the induction of the solenoid magnet at the end of the solenoid?

The magnetic field at end of the solenoid is half of that at its middle
