If the field changes linearly from 0.00 to 0.50 T in 0.80 s, what is the magnitude of (a) the induced “emf” E in the circuit (b) the induced electric field E, and (c) the induced current I? Answer: (b) The total length o ...

Magnetic Effect of Electric Current
... The direction of magnetic field can be identified using Right Hand Thumb’s Rule. Let us assume that the current is moving in anti-clockwise direction in the loop. In that case, the magnetic field would be in clockwise direction; at the top of the loop. Moreover, it would be in anticlockwise directi ...

... It affects motors, hydro generators and turbo generators. There has been an increase in occurrences and intensity of shaft current damages as machines became larger, particularly on high speed turbo generators. The build-up of voltage on the shaft and the resulting currents may damage bearings and c ...

... Earth’s surface is primarily due to its molten iron core. Effectively, there is a large bar magnet running through the center of the Earth. Oddly enough, the magnetic North Pole (of the bar magnet) roughly corresponds to the Earth’s geographic South Pole. We note that magnetic field lines (force lin ...
