Answer:
e. The net magnetic flux in this case would be equal to zero.
Explanation:
As per Gauss law of magnetism we need to find the net magnetic flux through a closed loop
here we know that net magnetic flux is the scalar product of magnetic field vector and area vector
so here we have
= net magnetic flux
since we know that magnetic field always forms closed loop so if we find the integral over a closed loop
then in that case the value of the close integral must be zero
so correct answer would be
e. The net magnetic flux in this case would be equal to zero.
Answer:
The current in the second wire is 4.4 A.
Explanation:
Given that,
Distance =7.0 cm
Current in first wire = 2.0 A
The magnetic field strength is zero at distance of 2.2 cm from the first wire.
We need to calculate the current in the second wire
Using formula of magnetic field
Here,
Put the value into the formula
Hence, The current in the second wire is 4.4 A.
