Where is the magnetic field due to current through circular loop uniform? Why?
Asked by Priyanka Margaret | 11 Feb, 2014, 07:26: PM
answered-by-expert Expert Answer
The magnetic field lines form circular loops around a point of a current carrying circular loop.
 
These loops increase in radius away from the point of the loop and the separation between two loops also increase as one moves away.
 
Hence, at the centre of the circular loop, the field lines will be nearly straight lines and the magnetic field at the centre is uniform.

Answer this:  Assertion (A): When radius of a circular loop carrying a steady current is doubled, its magnetic moment becomes four times.  Reason (R): The magnetic moment of a circular loop carrying a steady current is proportional to the area of the loop.  Select the correct answer from the codes (a), (b), (c) and (d) as given belote.  (a) Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).  (b) Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).  (c) Assertion (A) is true, but Reason (R) is false.  (d) Assertion (A) is false and Reason (R) is also false.

As we know, work done by Magnetic force is always zero in moving a charged particle./So it cannot change speed of charged particle. MY doubt is that, can magnetic force change direction of motion of charged particle?
