1. A conducting loop of arca A and resistance R lics at right angles to a spatially uniform magnetic ficld. At time t = 0, the magnetic ficld and loop current are both zero. Subsequently, the current incrcases according to I (t) = bt², where b is a constant with units A/s?. Find an expression for the magnetic field strength as a function of time.
