Design a current loop that, when rotated in a uniform magnetic field of strength 0.52 T, will produce an emf E = E, sin(@t), where En = 110 V and o = 120x rad/s. First, choose the number of turns the loop should have. (Enter a positive integer less than 100.) 0.1 turns Then calculate the needed area of the loop (in m2). (Use the number of turns you entered above.) m2

A 100-turn square wire coil of area 0.040 m2 rotates about a vertical axis at 1,450 rev/min, as indicated in the figure below. The horizontal component of Earth's magnetic field at the location of the loop is 2.0 ✕ 10−5 T. Calculate the maximum emf (in V) induced in the coil by Earth's field.

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). False v The size of the voltage induced in a coil through which a magnet moves is affected by the rate at which the magnet moves. The size of the voltage induced in a coil through which a magnet moves is affected by the strength of the magnet. True False vA 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, no emf is induced in the ring. True v An emf is induced in a long, but not infinite, solenoid by a bar magnet that moves inside it along the solenoid axis. True v In Faraday's Law of induction, the induced emf is independent of the resistance in the coil or circuit. True v If the magnitude of the magnetic field starts decreasing, the resultant induced current…
