00:00 The magnetic moment produced in a sample of 2 gram is 8 x 10-7 A/m2. lf its density is 4g/cm3, then the magnetization of the sample is
02:52 for an electron of charge e and mass m, the gyromagnetic ratio is
03:22 Two wires of same length are shaped into a square and a circle. If they carry same current, ratio of the magnetic moment is
07:59 A magnetising field of 300 Am-1 produces a magnetic flux density (B) = 0.3 T in a ferromagnetic material. What is its permeability in Tm A-1 ?
11:43 The magnetic moment produced in a substance of 10^-3 kg is 5 × 10^−7A−m2. If its density is 6 X 10^3 kg/m^3, then the intensity of magnetisation in A/m will be :
13:50 A straight wire current I is turned into a circular loop. If the magnitude of magnetic moment associated with the is M, the length of wire will be
19:18 A wire of length L carries a current i. If the wire is turned into a circular coil and kept in a uniform magnetic field , the maximum magnitude of torque in the given magnetic field will be
22:00 If Mo and Lo denote the orbital angular moment and the angular momentum of the electron due to its orbital motion, then the gyromagnetic ratio is given by
