The winding of the solenoid with 1000 turns per meter, core material with relative permeability 400 and carry a current of 2 A, the magnetisation (M) is approximately given by: |
$8 \times 10^5 A/m$ $3 \times 10^4 A/m$ $4 \times 10^5 A/m$ $2 \times 10^5 A/m$ |
$8 \times 10^5 A/m$ |
The correct answer is Option (1) → $8 \times 10^5 A/m$ |
