Which describes the magnetic field due to the displacement current in a capacitor?

a It is zero as the capacitor is being charged and then is nonzero after the charging is complete.
b It exists as the capacitor is being charged and then is zero after the charging is complete.
c It exists as the capacitor is being charged and then has the same value after the charging is complete.

b It exists as the capacitor is being charged and then is zero after the charging is complete.

Explanation:

The magnetic field due to displacement current is proportional to the displacement current . The magnitude of displacement current is equal to charging current of a capacitor. In the beginning , charging current is maximum but as capacitor is charged gradually , charging current decreases . Ultimately , it becomes zero.

Hence the magnetic field will also become zero in the end.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
