A short magnet is allowed to fall along the axis of a horizontal metalic ring. Starting from rest, the distance fallen by the magnet in one second may be
A short dipole is placed on the axis of a uniformly charged ring (total charge -Q, radius R) at a distance R/sqrt(2) from centre of ring as shown in figure. Find the Force on the dipole due to that ring
A short current carrying conductor is placed perpendicular to the axis of a current carrying ring as shown. The direction of force acting of the conductor is
The cambium ring of roots resembles the cambium ring of stem in
A short bar magnet having magnetic dipole moment M is moving along the axis of a fixed conducting (non magnetic) ring of radius R. The axis of the ring is along z direction. (a) Write the z component of magnetic field due to the magnetic dipole at a point P in the plane of the ring, at the instant the magnet is at a distance z from the centre of the ring. Position of point P can be defined in terms of angle theta as shown. (b) Write the magnetic flux through the ring due to the magnetic field produced by the magnet as a function of z. (c) Write the magnitude of emf induced in the ring at the instant shown if speed of the magnet at the moment is v.
