Questions from MODEL QUESTIONS with Hints & Solutions
A current carrying conductor passes through the centre of a metal ring normal to the plane of the ring. Is there a current in the ring when the current in the conductor is switched on and switched off? Will such current in the ring be seen when the current in the conductor is steady? Explain your answers.
A farmer claimed that the high voltage transmission lines running parallel to his wire fence induced large voltages on the fence and often becomes dangerous. Is it possible? Explain your answer.
A sheet of copper is placed between the poles of an electromagnet, so that the magnetic field is perpendicular to the sheet. When the sheet is pulled out, a considerable force is required and the force required increases with the speed. Explain the happening.
A coil of insulated copper wire is moved in a uniform magnetic field at a constant rate. An emf is induced in it.
A coil of metal wire is stationary in a nonuniform magnetic field, will an emf be induced in the coil?
A wirecoil carries the current . How will the potential energy of coil depend upon the resistance of coil ?
Do eddy currents cause sparking ?
A coil is rotated with a uniform speed in a constant magnetic field. Will there be induced emf and if so, can it be periodic ?
