Electromagnetic Induction
 

Electromagnetic Induction problem 6


A coil of length 50 cm is wound with 1000 turns round an alloy rod of Iron and Cobalt. Calculate the current that must flow through the coil to have a magnetic field with a flux density of 2 T in the rod?


The relative permeability of the alloy is 18000 and the permeability of free space .
