Question # 1

Does the induced current depend on the resistance of the circuit?

Ans 1: Yes the induced current depend upon the resistance of the circuit.
By ohm's law
I=e/R
Thus the induced current depends on the resistance of the circuit.

Question # 1

In a certain region the earth's magnetic field points vertically down,When a plane flies due north,which wing tip is positively charged?

Ans 1: When the plane flies due north in the earth magnetic field directed vertical downward,then electron will experience force in east direction,Thus west wingtip of the plane is positively charged.

Question # 1

Can DC motor be turned into DC generator?What changes are required to be done?

Ans 1: Yes ,a D.C motor can be converted into D.C generator.For this armature of the motor is to be coupled with some rotating body.Due to rotation ,magnetic flux through the coil changes so and emf will be induced at the output.Hence the motor acts as a generator.
