(a) Explain the terms: 'magnetic field strength', 'magnetic flux density' and 'permeability' of a magnetic material. Write their SI units.
A current carrying conductor is placed at an angle of 30° to a uniform Magnetic field of strength 2×10³ T. The length of the conductor inside the Magnetic field is 2 m and the current flowing through it is 1.6 A. Calculate the Magnitude of the force experienced by it.
(b) Distinguish among 'nuclear fission' and 'nuclear fusion'. Which one of them is used for release of energy in a nuclear reactor? Name one fuel used in a nuclearreactor.
(c) With the help of a circuit diagram, explain the working of a P-N-P transistor.
Define magnetic moment of a current loop. The magnetic moment of a current loop is described as the product of the current and the loop area. Its direction is perpendicular to
