The figure represents a thin conducting loop placed in a uniform magnetic field

Question

The figure represents a thin conducting loop placed in a uniform magnetic field directed perpendicular to the plane of the paper and inwards. Some of the following questions pertain to it. (Select True or False) TrueIf the magnitude of the magnetic field starts decreasing, the resultant induced current (due to the whole loop) flows in the counter-clockwise direction in the right loop. FaiseAn emf is induced in a long, but not infinite, solenoid by a bar magnet that moves inside it along the solenoid axis. True A current carrying conductor passes through the centre of a metal ring in a direction perpendicular to its plane. If the current flowing through the conductor increases, an emf is induced in the ring True The size of the voltage induced in a coil through which a magnet moves is independent of the rate at which the magnet moves. False The size of the voltage induced in a coil through which a magnet moves is independent of the strength of the magnet Due Friday April 06 11:59 am (EDT) Submit Answer Incorrect.

Explanation / Answer

The left loop is bigger and emf inuced in it is larger. So, induced current is counterclockwise. True

The flux is almost same so negligible or no emf is induced. False

Induced emf is independent of resistance. True

Net flux through the ring is zero as the field lines are concentric. So, there is no emf induced. False

Voltage depends on rate of moving of magnet. True

Voltage depends on strength of magnet. True
