Curl the palm of your right hand around the circular wire with the fingers pointing in the direction of current and the thumb gives the direction of the magnetic field. In this case the upper side of the loop may be thought of as:
Two square shaped metal plates of side 1 m, kept 0.01 m apart in air form a parallel plate capacitor. It is connected to a battery of 500 V. The plates of the capacitor are then immersed in an insulating oil by lowering the plates vertically with a speed of 0.001 ms\(^{-1}\). If the dielectric constant of the oil is 11, then current drawn from the battery during this process is
