Answer:
The magnetic field is
And the direction is
Explanation:
From the question we are told that
The magnetic field at the center is
Generally magnetic field is mathematically represented as
We are told that it is equal to 1mT
So
From the first diagram we see that the effect of the current flowing in the circular loop is (i.e the magnetic field generated)
This implies that the effect of a current flowing in the smaller semi-circular loop is (i.e the magnetic field generated)
and for the larger semi-circular loop is
Now a closer look at the second diagram will show us that the current in the semi-circular loop are moving in the opposite direction
So the net magnetic field would be
Recall
So
Using the Right-hand rule we see that the direction is into the page which is
