In an AC circuit,a solenoid is present. A bulb is connected at the end of the solenoid.
a)what happens when the swicth is on and off ?
b)lf an iron rod is inserted in the solenoid, what happens to the intensity of light?
c)lnstead of AC if DC is used, what happens during cases 'a' and 'b'.
d)which bulb shows more brightness,whether in AC or DC circuit?
What will happen during electro magnetic induction if the coil and magnet is moved simultenously? Will there be an induced E.M.F ?
What is the difference between flemings left hand and right hand rule ?Let me please know the different occasions when these rules are used?How can we understand whether which rule is applicable for a given instance?
what is mean by armature
which is the current responsible in DC generator?
what do you mean by Eletro Magnetism?
name different type of microphone and their uses?
What is mutual indution plz give an explaination
' Magnetic field is around a magnet and a current carrying wire, These are forces that attracts and repels ' ,But what makes this force? What is the cause of the force and what is inside each magnetic line of force.. , an electrone?

Q. What is this symbol?
if the switch in primary is on,will the bulb in secondary glow?justify
if the switch in primary is off,what will happen to the magnetic flux in secondary coil.how will this change affect the current and brightness of bulb in secondary coil
