Question
The magnitude field inside of a conductor is zero. T F The electric field inside of a dielectric is smaller than the field outside T F There are no magnetic monopoles. T F The induced emf in a wire depends on its resistance. T F The sum of the currents around a loop equals zero. T F The potential of a conductor is zero. T F It is easy to create magnetic field of 10 mT. T F For inductors in parallel, we add the impedance. T F We use the left-hand rule to calculate the direction of the magnetic field. T F Charge is conserved. T FExplanation / Answer
a) False.
The magnetic field inside a conductor may not be zero. Because if the the flowing current is unifoml distributed in the conductor then from ampere's law there will be cuurent inside the cosidered loop. so there will be a magnetic field. for a cylindrical conductor and constant current density the magnetic field varies proportional to radial distance inside the conductor.
b) True.
c) True.
d) False.
The induced emf in a wire does not depend upon the resistance. It depends upon the rate of change of magnetic flux. And this flux depends upon area of the loop, and magnetic field and they have no dependence of resistance. But the current in the loop depends upon the resistance.
