A solenoid has a core of a material with relative permeability 400. The wtndings of the solenoid are insulated from the core and carry a current of 2A. If the number of turns is 1000 per metre. Calculate (a) H, (b)M,(c) B and (d) the magnetising current `I_(m)`.

Text Solution

Verified by Experts

The magnetic field B is given by
`B=mu_(r)mu_(0) H = 400xx 4pix×10^(-7) (N//A^(2))xx2xx10^(3)(A//m)`=1T
