Electromagnetic Induction and Alternating Currents

Why does the acceleration of a bar magnet
decreases, while falling through a solenoid,
connected to a closed circuit ? [Foreign 2001]

Two identical loops, one of copper and another
of constantan are removed from a magnetic
field within the same time interval. In which
loop will the induced current be greater ?
[Delhi 2005C]

inductor, capacitor and resistor are 20 V,
20 V and 40 V respectively. What is the phase
difference between the applied voltage and
the current in the circuit ? [AI 2005

Peak value of emf of an a.c. source is E0. What
is its r.m.s. value ? [AI 2004]

Define one henry. [Delhi 2003]

Define the term self-inductance. [Foreign 2002]
