Just need numaric answer for these mechanic questions. see attached
See attached file for problems of resistance, tungsten filaments, current, emf.
The mutual inductance of two coils is 0.750 H. How do I find the average emf induced in the secondary if the current in the primary reaches 6.00 A in 0.0300s?
The length of a conductor linking a magnetic field is 0.060m, and the flux density of the field is 0.040 N/Am The conductor is moving down through the flux with a velocity of 1.5 m/s. What is the induced emf?
A circular current loop made of flexible wire is located in a magnetic field B; you may keep B constant or vary it. Describe three ways an emf can be induced in the loop.
A coil of 500 turns is wound on a wooden ring having a mean diameter of 8 cm and a cross sectional area of 1.5 cm^2. Assuming relative permeability of wood is 1, calculate the self-inductance of the coil and the emf induced in it when the direction of a DC current of 5A flowing in it is reversed in 0.2 sec?
