Question

What condition is specified for using \[\Phi=NBA\cos\theta\] as the magnetic flux linkage of a coil?

विकल्प

• The magnetic field is opposite to the area vector

• The surface is curved

• Every turn contributes equally

• The net magnetic flux is zero

Answer 1

The coil formula uses the same contribution from each of its \[N\] turns. Multiplying one turn's flux by \[N\] gives the magnetic flux linkage.
