There are 1000 turns /m in a Rowland's ring and a current of 2A is flowing in the windings .The value of magnetic induction produced is found to be 1.0T. When no core is present then magnetizing field produced in the ring will be |
1000 A/m 1400 A/m 2000 A/m 2400 A/m |
2000 A/m |
$ H = nI = 2\times 1000 A/m = 2000 A/m$ |
