Application type questions on uniformly charged infinitely straight conductors
Answers
Q1: Two identical circular loops P and Q, each of radius r and carrying equal currents are kept in the parallel planes having a common axis passing through O. The direction of current in P is clockwise and in Q is anti-clockwise as seen from O which is equidistant from the loops P and Q. Find the magnitude of the net magnetic field at O.
Q2: A circular coil of closely wound N turns and radius r carries a current 7. Write the expressions for the following:
(i)The magnetic field at its centre.
(ii)The magnetic moment of this coil.
Q3: A particle of charge q and mass m is moving with velocity It is subjected to a uniform magnetic field B directed perpendicular to its velocity. Show that it describes a circular path. Write the expression for its radius.
Q4:A long solenoid of length L having N turns carries a current I.Deduce the expression for the magnetic field in the interior of the solenoid.
Q5: A wire of length L is bent round in the form of a coil having N turns of same radius. If a steady current I flows through it in clockwise direction, then find the magnitude and direction of the magnetic field produced at its centre
