Question

state and Prove Ampere's circutul law.(in 3 marks​

Answer 1

Answer:

Ampere's law:

Statement: "The line integral of the intensity of magnetic induction field around any closed path is equal to μo times the net current enclosed by this path".

B.dl=μoi

→Let us consider a closed plane curve encloses currents i1,i2,i3 and i4 through the conductors as shown in the attachment.

Here,

→i1,i4=currents downwards-'+ve'

→i2,i3=currents upwards-'-ve'

→The net current through conductor is

→I=i1-i2-i3+i4

→So, The magnetic induction along the closed path,

B.dl=μoi
