A curent-carrying 2.0-cm long segment of wire is inside a long solenoid adius - 40 cm - 800 turns/m, current - 50 mA). The wire segment is oriented pependicalrly to the axis of the solenoid. If the curreat in the wire segment is 12 A, what is temagnitade of the magnetic ferce on this segment?

The value is  

Explanation:

From the question we are told that

   The  length is  

     The radius of the the solenoid is

     The number of turns per meter is  

     The current through the solenoid  is  

      The  current through the segment is  

   Generally the magnetic force is mathematically  represented as

At maximum

So  

Here B is the magnetic field is mathematically represented as  

Here   is the permeability of free space with value

So  

=>    

So

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

in four significant figures
