Question

Two circular loops
p and Q placed
with parallel to each other. A current
flowing through p. If this current is
increased​

Answer 1

Answer:

Now, as the current flowing in loop P is clockwise by using right hand thumb’s rule the direction of the magnetic field will be towards left and as the current in loop Q is clockwise then the direction of magnetic field is towards left. So the net magnetic field at point O will be the sum of the magnetic fields due to loops P and Q.Also, as the fields produced are at an equal distance to O, BP = BQ,So, net field
