A magnet is dropped vertically downwards along the axis of the Aluminium loop of wire lying horizontally. Will there be any difference in the time of fall if the wire is at room temperature and heated to below its melting point ? If so, explain. (Hint: Resistance of a conductor is directly proportional to its temperature).

1.	A magnet is dropped vertically downwards along the axis of the Aluminium loop of wire lying horizontally. Will there be any difference in the time of fall if the wire is at room temperature and heated to below its melting point ? If so, explain. (Hint: Resistance of a conductor is directly proportional to its temperature).
Answer» Solution :(i) CHANGE in the magnetic field (II) Dependence of induced current on RESISTANCE of the coil (iii) Dependence of resistance on temperature (iv) Force between induced current and magnet. (v) Dependence of fall in amount of current induced.
