.Draw the pattern of lines of force due to a magnetic field through and around a current carrying loop of wire. How would the strength of the magnetic field produced at the centre of the circular loop is affected if (i) the strength of the current passing through this loop is doubled? (ii) the radius of the loop is reduced to half of the original radius?

Answer:
Biot Savrat Law affects the strength of magnetic field induced due to current flowing through the loop. Explanation: (1)When the loop's radius is decreased as magnetic field strength formula is inversely proportional to radius of the loop, becomes double of the magnetic field strength.
The magnetic field lines are concentric circles at every point of a current carrying circular loop. The direction of magnetic field of every section of the circular loop can be found by using the right hand thumb rule. At the centre of the circular loop, The magnetic field lines are straight.
