L = N(Φ/I)
Where:
L is in Henries
N is the Number of Turns
Φ is the Magnetic Flux Linkage
Ι is in Amperes
This expression can also be defined as the flux linkage divided by the current flowing through each turn. This equation only applies to linear magnetic materials.
Hence, the correct option is (D)

Calculating Magnetizing Force

To calculate the magnetizing force of the coil, we can use the formula:
H = N * I / L

Where:
H = Magnetizing force (A/m)
N = Number of turns (10 turns)
I = Current (750 mA = 0.75 A)
L = Length of the coil (2 cm = 0.02 m)

Plugging in the values

Now, let's plug in the values into the formula:
H = 10 * 0.75 / 0.02
H = 375 A/m

Therefore, the correct answer is option 'D' which is 375 AT/M.
