Draw the pattern of lines of force due to a magnetic field through and around a current carrying loop of wire How does the strength of magnetic field produced at the centre of the loop be affected if a strength of the current passing through it is doubled b the radius of the loop is reduced to half the original value c the radius of the loop is doubled its original value and at the same time current passing through it is also doubled
