Question

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?​

Answer 1

Answer:

(a) strength of the currentpassing though is doubled

Answer 2

Answer:

(a) The strength of magnetic field is doubled as the current is directly proportional to the magnetic field.

(b) The magnetic field increases as the radius decreases.
